We are going to DL this weekend and I've started browsing the wait times on Mouse Wait to get a feeling for what I should expect. I noticed that a lot of times it looks like the meet and greets are closed. I've never been to DL as an adult so I don't really know how those work - are they always open? Only certain hours? Is it predictable? I have 3 and 5 year old girls and meeting the princesses is a priority! We're going to do lunch at Ariel's Grotto one day where I'm hoping to meet some of the classic ones but I'm guessing Rapunzel and Merida will just be at the meet and greets - any advice?
