I took my dd17 for a mom n me trip and stayed 2 days at CBR and one day at GF in Sugar Loaf Club. The side facing the marina looks lovely and you can see the monorail too. I didn't get that request and had 6310. It was to the left of main entrance facing the pool. It had a tree in front of it and you could see the crane (construction) too. It was on the 3rd floor and because of corner location ( look at picture of building) it was very private. Unless noise or smell of water bothers you I think marina side better.
Housekeeping was great and let me stay in room until 2p on checkout day!
Food offerings were good and restocked quickly too! The negative is blandness of the club space.
Location really was nice, pool, marina, main bldg all close by!
We really enjoyed our stay! We have only stayed club level at CR and hope to try Poly next. We love all monorail resorts!
Have a great time whatever you decide!
