Keep in mind that they are only valid in the year they are purchased.. buying one now - expires end of 2004 - I see your a year away from going...
the entertainment books go half price after may too.
I called the royal pacific resort via the 1800beastar number and gave run down of discount/club cards. The ENT rate was the best next to the APH rate for the day i was booking.
These may be comparable to the 'special rates and promo's' run for UK tourists.
Even so... for another trip my daughter is taking - we called the 800 number, the hotel, and checked hotel.com with AAA and AARP and ENT and a gazillion other rate codes and none of them would even match the expedia price of 106 a night.. they were booking 159+ with no perks. silly.
happy vacations!
