@Wells Larsen back in 2018 we were at S/D for vacation and there was a very large food conference, one room across from us was a host room and used for some small break outs. Other then feeling sorry they were all wearing suits, they caused no issues for us. We could hear them come and ago a bit but really nothing worse then a family leaving their room. We did see how busy the restaurants and bars for the locations at S/D were. Il Mulino was packed and busy, the Crescent Terrace outside of it was very busy too. On the good side of it, those hotel guests were not getting on the buses or boats, so we had no issues at all getting to the parks. Some may have had families but I'd so most were 100% there just for the convention. They did get on the buses to Disney Springs in large numbers, but that was it. Having attended a conference at Coronoado Springs I'd say the transportation isn't an issue, we had our own buses the one night we went to MK and on the trip back they had extra buses for CSR guests that night. I wouldn't be bothered by a convention for adults... a group of kids would be another thing - and I love kids and love seeing them having the chance to attend competitions and conferences, I just don't care to pay be at the same location.
