I don't think they have been bad, especially during the week. We have been going the last week of May. Of course the weekend is busier, but we make use of FP when needed. I have seen them run out of them on Indy and Splash, but that was on a weekend later in the afternoon. I haven't been to DL during the really busy times, but I think that May is a perfect time to go. We are late enough to miss spring break crowds and early enough to miss the summer crowds. The weather is beautiful, but then it is So Cal! Have a great trip!
