We just booked a last minute trip to WDW next week. Our kids are each bringing a friend so we will have two DG11 and two DB9. We will be there on Friday, Saturday and Sunday. We want to go to Blizzard Beach one day and the parks the other two days. I never been to Disney in May, any advice for what to do on which days? And curious what crowds are like this time of year. THANKS!
