Is there a limit to the number of PS arrangements someone can make in total or for any given day? There are a couple of things we really want to do, but the days on which we do them will be somewhat dependent upon park hours (which are not established yet for May...grrrr). My PS window begins 2/16, so I'm thinking if the park schedules haven't been established prior to then I'll simply make all of the PS arrangements I want for every day and simply cancel reservations once I am able to finalize my itinerary. Any thoughts?
