We nedd no reason to return, anytime. Irregardless of new attractions or celebrations, its the complete total relaxing, enjoyable vacation experience and destination on this planet for us. We definetely return every year, and some times twice and three times in a year. We have gone other places a few years back, but compared resort, price and things to do, WDW wins hands down. Myrtle Beach ocean resorts cost about the same as a Disney resort but all you have is a hotel and ocean, thats boring after 2 days, then its in the car, driving up and down the strand looking for things to do and them things cost ya money. At Disney, you do not need a car for your whole stay. Everything is included, transportation, 2 water parks, 4 themed parks, tons of exotic dining, themed resorts and pools, night life and clubs, just everything you can imagine, rolled up into one big place, secluded and priced to have it all your way.
Really no reason not to return as many or often of times as you can. We make up reasons and excuses to go back and we been doing it since our first trip, in 1977. Back then, even with ony the one park then 2 it had what we wanted in a vacation destination and just only got better and better every year, even though our 2 kids have grown up, and with Disney, we're in our 50's, and continue to go back more now then before. Join the fanatics and Disney lovers and become a convert, its magical.
