We.re going the week of 6/23. From the guidebook and the boards I'm getting apprehensive. Are the crowds that bad i.e.1-2 hours per attraction? We plan on being there at openiing,staying till lunch,take a break and go back late afternoon about 4PM. Is it even worth it toi go back in the evening? Also,we're going with small childred 4 and 6.
