It has been brought up often but from what I understand things have changed quite a bit since we’ve been to them 6 or so years ago. Would like to stay on premises for each, maybe 2 days disney and 2 days universal, or something similar. Kids are 18 and 15. Probably most interested in Epcot and animal kingdom for Disney. Advice on which properties get you the best fast passes or whatever they are called now? Also thinking either very early June or very late July. Thoughts on which is better? TIA!
