Hi - Next month will be our third time to Disney as a family and we haven't done Fantasmic yet. Kids will be ages 7, 4 and 2. The latest dinner reservations we can get are 3:45 p.m. I'm not sure how this works - what does this guarantee for us - or are we just better off doing a general dinner reservation for like 5:00 p.m. in HS? I'm lost on this Fantasmic thing and how it works. We'd want the early show since it will be our first day there and everyone will have been awake since early a.m. Thanks.
