I like that when you check in if your room is ready, which is has been past 2 trips, then the bellman brings you right to your room where you can relax a few minutes-even grab a snack from the lounge before you have to deal with the paperwork.
I also love that one adult can take the kids to the lounge in the morning while the other gets ready for the parks. I like the lounge offerings and especially like the convenience of getting milk and juice boxes for the kids without having to run the the snack bar. I also liked that they had paper coffee cups with lids so you could grab a cup of coffee as you headed out for the day.
I like the turndown service (available by request at all deluxe resorts not just concierge). Not only to they turn down the bed and leave chocolates but they bring fresh towels and best yet with a kid in diapers they empty the trash.
I liked that they were able to mail a package of stuff home to me. I used a box I had sent stuff to the resort in but they could have gotten me a box and supplies if needed too.
I like that you need a key to get into the building-makes me feel safer.
I LOVED the cake they ordered for my DS's birthday at CP and then they surprised him with a cake in the room too complete with party noisemakers-what better way to spend a birthday-at WDW and 2 cakes!
My DD LOVED the strawberries, PB&J's and cookies. My DS LOVED the mini-muffins.
Luckmommyx2-the concierge services no longer offer bottles of water for the parks. The Poly has glass bottles of water that you can take to your room. I'm doing a limo this next trip and will do a grocery stop and buy bottles of water, Pepsi for my DH, chips for DH, and cheese slices for DD (they have cheese at lounge but DD likes Velveeta slices). For the evenings they had cheese & crakers and veggie dip everynight. The offerings vary but I remember chicken satay, chicken lomein, ribs, ...everything was great! They also had soup-the homemade chicken noodle soup was delicious! I can't help you with the GV question as I've always stayed LV. I keep saying I should try GV but with the kids so young I want to be able to see EWP & fireworks from the room.
