How do you plan your trip/days with younger kids to best avoid exhausting them? Mid-day rest time and back to a park around 4:30 or 5:00 for an early dinner, a few rides and leave around 7/7:30 or stay in the park all day but do an early (5:00 or earlier) dinner and back to the room? My daughter just turned 4 and my son will be turning 6 while we're there at the end of January. Thanks!
