The Flatotel in New York City offers "Guys Getaways" from $489 per night, including suite accommodations, drinks on arrival, cheeseburgers and fries, and unlimited pretzels. While the rate seems steep, suites typically go for $630 per night. So if you'd like to stay in one of the Flatotel's suites, even if you don't think you'll take advantage of those "unlimited pretzels," the package offers a bargain with savings of $141 per night.

Remember, for the splurge categories, it's important to compare apples to apples. Naturally, suite accommodations are going to cost much more than a standard room. Be sure to compare non-package and package rates for the specific room category that interests you to determine the best value for your trip.

Consider your tastes

The lesson here is, don't rush to book. You may save time, but you may spend a lot of extra money, too. Dig beneath the surface and decide what the components are worth to you: Could you get them cheaper if you purchased them on your own (or not at all)?
