June 17-21 will be our first time staying off property (Sheraton Vistana Resort) with a rental car. Previously, staying in the bubble, we've used Disney Transportation or, last time, used Uber to get from Dolphin to a drop off at GF, then monorail to MK. This was so convenient, as we shopped and grabbed a snack at GF before jumping on the monorail, and we were able to stay away from the crowds at Ticket and Transportation Center. So, I'm wondering, if we use our rental car, could we pay to park at Poly, grab some Tonga Toast from the QS there, then get on the monorail to MK? I'm sure I'm not the first one to come up with this plan to bypass the TT center, but is this legal?
