If you're looking for something with North America, places like Disneyworld and Hershey Park are great. If you're looking for something more low-key and romantic, New Hampshire and Pennsylvania have some great hot spots.
There's always the option of a cruise, where the prices are more often than not, all-inclusive and you can choose one of so many destinations out of the country. It all depends on your budget, where in the world you're looking to go, and what kind of exciting things you would like to do and see.
I've used www.usairwaysmastercard.com and they've had great deals on crusies, hotels, flights, and attractions. That site also allows you to compare prices of other dates and times of travel. Enjoy!
