Our ceremony is in Epcot, so we have the mini-bus and limo included in the package. We have extra people coming to the lunch who aren't coming to the ceremony, so after the ceremony the bus will go back to Saratoga Springs where the ceremony and non-ceremony goers will be meeting up for an in-suite "pre-reception," then the bus will take everyone to Disney Springs. We might have 1-2 who take the boat over instead if the bus can't fit everyone, but the boat from Saratoga drops off right at Morimoto. Or, since I have no idea what Disney Springs looks like and if the bus can get close, everyone will take the boat from Saratoga Springs. Then after lunch, people can take the bus back or take the boat or go wherever else they want.
That's another advantage of a non-Disney reception - the ability to invite more people! It seems they're pretty strict about having the same number of people at the ceremony as at any other events planned through DFTW. I had a lot of family who wanted to celebrate with us (and really just wanted a reason for a Disney trip

) than the 18 allowed at the ceremony, and these people were totally fine not coming to the ceremony because they understood. So, these people are coming to the dessert party the night before (which I planned through DCE, not DFTW) and the lunch after the ceremony, which I couldn't have done had I planned through DFTW. If we hadn't had to do a Friday ceremony because of DF's job, I might've done mini-Wishes, but this all worked out really well. But I've really enjoyed having the limit.
As far as S&D weddings, my mom met with one of their planners while in Orlando earlier this spring and loved them. She said they were really nice and really eager to help and answer questions, and she said that Crescent Terrace is beautiful. She also thought that Il Mulino there at S&D would've been an awesome space for a reception. If we hadn't gotten Epcot on the day we wanted, I'd have done S&D instead, no question.
