we timed our visit to the AKL concierge so that we could go on the Sunrise safari...
all 4 of us felt the safari was well worth the effort..
also the AKL concierge lounge is one of the nicest at WDW in terms of the lounge itself and the food offerings...
the check in is also nicely done at the AKL (each resort concierge has its only check in system)....at the AKL, if you come during the hours that the concierge lounge is open, the bellboy takes you straight to your room, handing you your welcome packet with your name on it)....he tells you that you can walk over to the concierge lounge at your liesure to check in....
that's quite nice....
but we found the check in process there to be particularly slow.....there was only one CM on duty when we walked over to check in.....since it's in the lounge, you can have a drink while you're waiting..
at the GF concierge the check in is run differently.....we drove from the airport...at the gate we had to give our name....no doubt we were on his list as concierge and he called ahead because when we got to the unload area, there was already a special person from the concierge staff waiting to greet us (hello XXXX, I'm Joshua from the Concierge, welcome to the GF.....).....it was very nice...
the bellboy took our luggage, the valet took our car and the special concierge CM escorted us to the concierge floor for check in....you definitely feel special.....and there were 3 CMs on duty at check in, so things went very quickly....and as everywhere at WDW, the CMs in concierge are wonderful....
however to answer your question as to whether concierge service is worth it.....no, concierge service probably isn't worth it in terms of dollars and cents.......but it is nice if you like to splurge on vacation.......and also, at the AKL if you stay concierge you can go on the sunrise safari, which we very much enjoyed.....
