I will say that dealing with GG was a pain in the .....neck! I thought it was only because we were DVC and the two systems don't communicate with each other. The only benefits I found was the special events and room location. We only did the Fireworks Pirate cruise, but it was fabulous!!!! The other benefit, room location. We were able to be right across the hall from my MIL and SIL. And, since the rooms were blocked together, and SIL checked in a few days before us, our room was empty for 2 days and ready when we checked in at 9am on a Sunday! As far as ADR's, I/we made some together and some separate, but never through GG.
