On the serious side, just about anywhere in the US can be really fun and beautiful. Nolans idea about the Grand Canyon and the southern Utah national parks was a great idea. I would recommend the north rim of the Grand Canyon and then all 5 of the Utah parks. Here is info:http://www.utah.com/nationalparks/http://www.utahnationalparks.com/http://www.fiveutahparks.com/While you re at it, head up to Yellowstone. Fabulous!!
Grand canyon, Zion national park, yellowstone national park, Oregon, Washington, Canada is also very fun, and not too expensive, California, Utah, Going to beach on Gulf of Mexico, Mrytle Beach, Chicago, New York,
Disney xD
Yellowstone and Grand Teton parks in Wyoming are pretty cool.
