We don't. my mom who goes with us says it is more exhausting the back and forth.. We usually are late afternoon to close people. An afternoon break for us would mean be being at the park super early ( for us 9am) staying for 4 hours and a break for 4 and then hitting until close.. This means not hitting the sack until 11pm or midnight usually. No way after a day like this could we get back up for another early day.
My kids, nor us nap anymore... I can see a break working for families with smaller kids who NEED a nap and can make up for early mornings and late nights.
but what we do, do is the water parks first at 10am for a few hours and hotel to shower change, rest up and then a normal park... does this count?? Here we have a car and drive to the water parks,, super fast and easy with parking, fast in and out.
