I totally agree with the past posters. For over 20 years, we have always gone to the parks early, come back to the resort and swam or taken a break and waited until evening to go back to a different park for the second half of the day. most of the commando style people have had it for the day by evening, or people staying off site are heading for the parking lots, I always comment on the line of guests leaving the MK for the monorail and the line is usually back to the park, thse are the off site guests or driving guests. We most always stay at the Poly and return either by boat or monorail with no wait. In the evenings the pools are mostly empty, few kids, some adults lounging but really pleasant through the night. Seems when the life guards are gone for the night most guests are pooped and stay in. We usually meander the grounds, take our cooler or a bottle of wine down to the pool area and relax and reflect on the day and discuss plans for the next day.
Going commando reallytakes the stamina out of a person, espically during the summer months. After all our trips, over 30, we have seen that and done that and casually go about the parks doing our favorite things, mostly seeing everything but at a casual pace and that noon break, getting out of the mouse race at the parks, is our lifesaver. Plus, on property, the resorts are themed to the nines and the late night pool dip with friends is beneficial for rejuninating the soul and instilling the magic of Disney World.
