We're going to WDW from October 10-17, and it looks like it's going to be very hot! We rented a Polar Patio at Blizzard Beach last year in May and really liked it. There were plenty available same-day, but I know October is busier. Does anyone know if the Polar Patios or Beachcomber Shacks sell out at this time of year? I prefer not to make advance reservations because of the possibility of rain.
