So, SSR has a bunch of QS options and they’re scattered about, and the rooms that are the furthest from them are the closest to Disney Springs. I don’t think it’s a disaster to stay there. But I also would suggest WL. BRV is a separate building too though and also will involve a bit of a walk from the farthest rooms.
My real suggestion for anyone with a baby is go to
Disneyland instead, it’s approximately 100 times easier for children under 3, with its smaller parks, very close hotels and dining, plus with zero on site perks of importance, you’ll way more than make up the difference in flights with the hotel savings. There’s at least 30 hotels within the same walk to the 2 parks as Grand Flo is to MK. And it has the same number of attractions in 2 parks as WDW has in 4 (seriously that’s true).
