19、esh seafood by the ocean, amazing restaurants in great cities, unlimited breakfast buffets at the hotel, that ice cream/candy/cake/jambalaya that you remember as a child and come back for every few years.

23、These kites can be easily assembled and then taken apart, making them perfect for traveling. Youll give your upper body a great workout as you struggle to control the kite. You may also have to run or walk to keep the kite in the airor chase it down once it plummets to the earth. 13. Schedule an act

24、ivity-based vacation. Ready to commit to even more action? Wrap your entire vacation around an activity, such as sailing, skiing, hiking, biking, or exploring.
