To save money while staying in a hotel, forget about the vending machines and room service. Instead: pack snacks.
Before booking a room, check to see if the room is equipped with a mini-refrigerator. If it isn’t, bring a cooler packed with ice. Put things inside it like cans of soda and bottles of water, fruit, cheese and sandwiches. You can refill the cooler with ice from the ice machine in the hotel. After all, there’s usually an ice machine on each floor directly across from the vending machines.
The money you save on snacks can be spent at restaurants and area attractions!
