We didnt use the club. Luckily we had my mother along to take the kids out for the night.
Like Anne said, its a quick walk to Epcot from YHS. Y&B clubs, BW & Swan & Dolphin are all located around the lake and are all in walking distance of each other. Epcot & MGM are too, but depending where you are on the lake, the walk could be a little longer to these places, especially MGM. There are also friendship boats that run between these places. Usually walking is quicker though.
As for the romance factor, I suppose it depends on your idea of romance. For us, anywhere without our kids is a special night out. I thought dinner was somewhat romantic, especially since we were seated in our own little area for most of the meal. It was quiet, DH & I got to talk without being interrupted, we were dressed a little nicer than usual in WDW and had a very good quality meal. That all made it special. The walk around the lake as the sun was setting also made it romantic.
We then went to Epcot for Illuminations and then to Jellyrolls for some fun. It was really a great night.
Enjoy your night out.
