My family stays at Shades of Green frequently, Peter. It’s a gorgeous resort and represents such a great value for eligible Guests. Don’t skip the ice cream in the lobby; it’s a great treat after a long day in the parks!
I would encourage you to double check the bus schedule upon arrival. You may find that updates have made it possible to get you where you want to be. If that is not the case, you definitely can walk the short, pleasant pathway to
Disney’s Polynesian Village Resort. Once you get there, you will want to look for signs that point the way to the Transportation and Ticket Center. You will be able to
get to any of the parks from that spot. Based on your description of your traveling party, I’d plan in an extra 25-30 minutes for the walking time from Shades of Green.
If a private ride share service is not an option and you opt out of the bus service at Shades of Green, this is the next best solution. I hope it helps!
