We are planning our first HP trip to celebrate my son's birthday 1/23-1/26. Shockingly, I see Sapphire Falls and Royal Pacific are practically sold out (and reservations claims the other hotels are similarly booked). Hotels are relatively clear the week before and the week after. His birthday is during our trip and is a special request, so we can't move weeks. Despite the assurances of various crowd calendars, it's looking like HP will be packed that week! Should we get xpress passes (or move to a hotel that gives them while still on sale) - or is this a convention? We are Disney folk and don't have any wisdom for Universal planning. Thanks!
