We're headed for trip 44 in 70 days and how we plan out our stays is fairly easy. We use no tour guides or subscription services, but take advantage of the morning extra hour and some evening extra hours. Those set up which parks on which days, that extra hour in the morning is a blessing....you can get so much done and be out before the masses arrive, then you can have a leisurely day at the pool before heading back out. we're not people that stay in a park opening to close, we enjoy the resort, pool and amenities and plan time to do just that. Granted our stays are 9-12 nights but we enjoy having no schedules, maybe 2 ADR's and flying by the seat of our pants.
We always plan a down day about mid trip, wife goes off and does her shopping thing, I lounge around the pool, enjoying a book and some drinks, we may play alittle putt-putt, catch the show at POFQ and boat to DTd for dinner or a movie.
Like I stated, nothing too complicated, park hours rule for us, food is immaterial ( TS meals at Disney are mediocre at best) relaxation time and when we tour a park, we go in one direction and catch every attraction that comes along (no criss-crossing the parks to certain attractions) and when we return to that park , go in the opposite direction. Works for us!
