Hi Sandra,
While I have nevered stayed at the S&D, I would not hesitate to, especially at that rate!
We were booked to stay at the Swan last January with an Entertainment rate of $165.00 for a Junior Suite. About a month before we left, I found a "promotional" rate on the internet at the Y & B Clubs for $174.00. The YC had always been my first choice so we did stay there and had an amazing time! For the record, my kids really liked the feel of the BC more but I wanted a guaranteed full balcony which the BC doesn't have.
If we can get a good rate, I would love to stay at either again next March when we go back, as well as at the BI. However, if we can't get a rate under USD 200.00, we will definitely be staying at the S or D. The location just cannot be beat! We loved the proximity to Epcot (we could see Illuminations if you leaned over the balcony just so....). The boardwalk was great for restaurants or even just a stroll after the parks had closed.
A lot of people feel that the S&D are lacking the Disney "magic" but when you are in the center of it all, I don't see how that can be. Also the added perks of staying at a Disney owned resort weren't all they were cracked up to be in my opinion. The Mickey soaps really made me itch (I have very sensitive skin) and my husband thought the Mickey wakeup call was so &*@% annoying (his words) first thing in the morning...LOL. The kids never even heard it because they never heard the phone ring, they were so tired! As far as charging everything to your room, we don't do that anyways as we like to know where we stand financially at all times.
My biggest worry about the S&D would be the Grotto pool. I have heard that while it is heated, it never gets quite warm enough to swim if the weather is a bit chilly. Storm-a-long Bay was like a bath even when it was only about 60 deg outside. Also, I have heard that they will close the pool for private parties (conferences) now and then and chances are, you will not know this until the same day.
Overall, I don't think you could go wrong staying at the S&D.
