...is that while the concierge can book everything for you, you do not receive preferential treatment simply because you are concierge. the first time we went concierge (cat 3), the concierge had us "pre-booked" (with absolutely NO contact with us prior) into palos the first night (of the 4-night). when we informed her we wanted the last night, she was unable to switch our "pre-book." dh took it into his own hands at that point and was (within a day) able to switch it to the day we wanted. he just has that ability to get the impossible done.
after that, we learned that while concierge is nice, you are still better off doing your reservations yourself. so, since then, dh goes to palos to sign us up while i either sign youngest ds into flounders or stand at excursion desk (pre-pre-booking) to get our excursions.
it's just not worth it to us to trust we'll get the palos ressies and spa ressies we want in march by waiting for concierge to handle. we will, however, use them after the first day if we want to try for additional palos' brunch/dinner or need anything changed.
