The Yacht Club is a conference resort, do to that you will find many folks in suits from time to time when a conference is happening there. It can be a little disconcerting to walk in from the pool in your swimsuit and find a gaggle of business folks in the lobbY. Personally doesn’t bother me all that much, lol. I used to attended the Lotusphere conference every year and always tried to stay at the Yacht Club. The Beach Club is a little closer to the EPCOT entrance and that is nice, it is a 5 minute walk at most.
I am such a YC nut, that I bought a set of shower curtains from the Yacht Club on eBay, just so I had that Disney feeling in the morning, it actually makes the early morning a little more bearable.
