Save $400 by going to the beach … I wish it were always this easy!

Hilton’s trying to make it as easy as possible for you to soak up the sun this summer. Its new deal in Puerto Rico will set you up with a free fourth night if you pay for three. Even better: the three nights that will cost you only start at $139 each. All in, you’re saving up to $400 a trip. Resort credits are offered for golf, dining, spa treatments and other activities.

And, it keeps getting better. You could also pick up a bonus certificate for a free night down the road if you book by July 15, 2009.

The four participating hotels are solid: El San Juan Hotel & Casino, The Waldorf Astoria Collection; El Conquistador Resort & Spa, The Waldorf Astoria Collection; Conrad San Juan Condado Plaza and Caribe Hilton, San Juan. So, it’s not like you’re being given a low price at a low-end hotel. This is strictly top shelf.

The catch? The promotion’s only good through the end of September.

One-day sale from Intrepid Travel starts now!

Intrepid Travel puts together some amazing trips, and today’s deal will make them even more accessible than usual. For the next nine hours, trips will be discounted deeply … all Intrepid trips … more than 400 of them. Price cuts range from 15 percent to 60 percent in this rare opportunity.

Trips departing soonest, of course, come with the greatest price breaks. Book an excursion that leaves in July, and you can generally knock 60 percent off the price. Those taking off in August can net you a savings of 30 percent, with the rest of the year’s trips 15 percent off.

The sale starts now and runs until 7:30 PM this evening. Each includes all accommodations and land transportation, some meals and a guide.

After the jump, you’ll get a sense of how much you can save.

Inca Encounter: this nine-day jaunt from Lima to Cuzco in Peru is only $664, down from $1,660

Road to Budapest: spend 15 days going from Vienna to Budapest for $692 – instead of $1,730

Kenya Adventure: eight days in Kenya will cost only $604, rather than $1,510

Favorable fares may be coming to a close

In past years, Memorial Day signaled the end of sweetheart flight prices. This year, a sinking economy stretched the deals a bit longer, but experts say the good times may be coming to a close. Remember the problems last summer, with higher prices blamed on jet fuel? Well, we could see the cost of oil work the same dismal magic this summer.

Rick Seaney, CEO of FareCompare.com, cites recent fare increases of $10 to $20 per roundtrip as an indicator that we are the brink of an upswing. But, these are counterbalanced by new lows elsewhere. A recent survey by Travelocity shows ticket prices down 17 percent for trips between Memorial Day and Labor Day. So, buyers and sellers are locked in a silent struggle to determine how much your next vacation will cost.

With an eye out for possible deals, customers are waiting, booking their flights 86 days ahead instead of the usual 90. While this doesn’t seem like much, it takes a lot of last minute purchases to bring the average down.

Even if airline fares are coming back, you can still take advantage of the lows now. If you’re thinking about taking a vacation, stop … and take action instead.

Gadling Take FIVE: Week of June 20-June 26

With a week where we’ve added a new blogger to the Gadling fold, I didn’t want to pass up the chance formally give Stephen Greenwood a hearty welcome. He’s going to be dazzling us with posts from his current home in Hong Kong. Tune into his Dim Sum Dialogues.

This has been a busy weekend. With ComFEST, the mega community arts festival taking over Columbus’s Goodale Park and terrific weather for each day of it, it does indeed feel like these are the days to enjoy oneself.

Here are five stories you might have missed:

  • In Amsterdam, a branch of Russia’s Hermitage Museum opened. Head there and you can see items that once belonged to the Russian court. As Kraig Sean mentioned, what isn’t covered is how the Romanov’s lost power. The thought of the family being lined up against a wall and shot by the Bolsheviks, still gives me pause.
  • Willy’s post on 10 things to do on Jost Van Dyke in the Virgin Islands has me wanting to head there for an eco-excursion.
  • If you aren’t feeling hungry, you will be after reading Jeremy’s post on eating brunch in Kingston, Jamaica. Jeremy’s adding posts on Jamaica to his lush series, Undiscovered New York.
  • Catherine’s post on Geographic Expeditions deals on travel caught my attention. I highly recommend guided tours. They are worth the money, particularly if your days off are a precious few.
  • As a New Yorker who sizzles in the summer, Tom is on the lookout for ways out of Manhattan and chances to cool off. He’s summarized the deals he’s found in New England. You don’t have to be a New Yorker to enjoy them.

Also, we’re running a new series on airport layovers. There are a few more to come. Annie’s post on Amsterdam this past week has one tip that did last December.

Biggest Hotel Sale Ever to combat swine flu travel fears

If you are after a bargain, Mexico is where it’s at. We’ve posted about how a group of hotels have a deal for those who do get swine flu from their trip to Mexico. But since that probably isn’t going to happen, there are deals for those who don’t get sick.

There’s a “Biggest Hotel Sale Ever” campaign in Mexico through Expedia. In general prices are 26% cheaper than this time last year. Resorts also have deals on spa treatments, dinners and alcohol, so check out a resort to see what you can snag.

In case you’re worried about catching swine flu, check out this AP article . As the article explains, getting swine flu in Mexico is a long shot, and people have begun to see that these deals are not to be missed.

Here’s my take. There’s a lot of sickness you can get in all sorts of places, but they don’t end up on the news. I’m not saying that swine flu is a sickness to pooh pooh, but in reality, a person can get sick by heading to any place that has a lot of people milling about. Staying home sounds boring.
