The short answer - yes, DH and I did this back in November. We were in Florida just of the weekend with DH's brothers. We were staying about an hour away and only there for a very limited time - but I just couldn't be so close and not visit Disney at all, so...the four of us took a drive over and got to the Contemporary just in time to see Wishes! Afterward, we went over to the Outer Rim for a few drinks and appetizers. At about 11 we decided to find out if it would be ok to go up to CG, so we went over to the desk and explained that we just wanted to go up for a few drinks. They said no problem, and took us right up! The bar/lounge area wasn't very crowded, probably due to the late hour...so I'd have to agree with a previous poster - try it off-peak hours for dinner. But I'd suggest going later, it's a better view at night.
