I have no answer, but am SUPER curious about the replies you receive.
Our family would like to spend a couple of days at Disney pre-cruise. I had hoped for either Swan or Dolphin, since we will only be visiting Hollywood Studios and Epcot, but there is no availability at either. So, now we think the Disney Springs area is the way to go, since we can use the Hilton shuttles to the parks and also walk over to DS. For our June 2022 dates, the price difference in the two properties is so little that we are struggling with the choice.
The reviews seem better at the Hilton Buena Vista Palace, but like you, we won't be spending time at the pool. The walk from Hilton Orlando Lake Buena Vista to Disney Springs seems to be much closer.
