My families trip is not nearly as exotic as yours but we finished our bookings yesterday.
Disneyland on Memorial Day Weekend. As horrible as that sounds.... there is a dance competition that weekend and the crowds are not as bad as you would think. Dance people take over the hotel. They have brought back early entry for those staying in the Disneyland Hotel.
We already had the rooms... had to get those back in January... but yesterday we got the tickets into the park, some dinner reservations, a few other things so we're done.
We won't be diving,
, but we'll get wet on Splash Mountain and Grizzly River Run. - JamesJM
