My 3 yr old LOVES Remember!
Just remember to be patient with them if there are possible delays. If it's a day when the fireworks are set to go off at 9:25, then the latest that Anaheim will let them complete the show is 10pm. If there are wind issues - which has been happening a lot lately, they will send recorded delay messages over the lodspeakers until 9:45. At that point, they have to cancel.
Another thing to note is that Fantasyland won't re-open until after the fire marshalls have done a thorough walk-through of the area. The quickest way to get back in there is from the Parade route path between the castle and the Matterhorn, then hang a left at the teacups. There is a secondary rope to get Peter Pan. (Done this way too many times...)
Also, don't be bummed if they also have to cancel in the middle of the show. We were at the 4th of July show, Friday night, and they had to stop it in the middle. Such as shame, as they we only set to do it one night (we wanted to go back tonight - it's 2am now, and they said they were back on with Remember), but it was such an expensive holiday show, that they had only allotted for one night's performance of mortars. What we did see of it was phenomenal! It made us want to go back next year to catch it again.
