You're right about the price at SOG. Plus the rooms are MUCH BIGGER. BUT my biggest complaint about the hotel is there is much of a Disney feel to it. To be honest, the hotel could be ANYWHERE. The only Disney items are the Mickey statue in the lobby and Mickey shaped pool.
I always thought the buffet at the hotel was a good bargin but after eating there a couple of times I realized how much I didn't like it. Trails End buffet is MUCH BETTER and either very comparable in price, if not cheaper!!
I also thought it was odd that the 'other' pool (it always seemed like the Mickey shaped pool was out of service while we were there) is now a SALT WATER pool....!?!
Plus the buses are OLD and the bus service is VERY POOR. If you do stay at SOG I would highly recommend just walking across the street to the Poly and taking the monorail. Of course when it's 100+ degrees even walking to the Poly is a trip in and of itself.
Anyway, after staying at various Disney hotels....SOG is now my LEAST favorite. If you really want to save money, I would recommend the Pop Century. It's even cheaper than SOG.
