No, none of the Grand Villas are in the lodge and all of them have the entrance on the 2nd floor of their building, so you'll need to go up 2 flights of steps to get to the front door. In addition, the master BR is the only BR on the main floor of the villa except for the sleep sofa in the living room. GVs are located in bldgs# 16,18,19, 28 and 30.
There are accessible 2BR lockoffs in the lodge with elevator access to all floors, but the lodge is the only building with elevators. The GVs are more like the ones at OKW, SSR, AKV, BLT and BWV rather than than the stand alone 3BR Beach Cottages at VB.
You could call MS to see if you could get a 2BR and Studio in the lodge instead of the GV if stairs will be an issue.
