Okay, my father is retired USAF and my family has stayed here multiple times since say 1990-ish (as far back as when it was the Disney Inn). I love the renovations they did on it and we have stayed about 4 times since the renovations, the last being in Aug of 2012. I love it there. I am sad that next time I go back I won't actually be staying there, but then again I'll be staying at an awesome Disney Deluxe DVC (so I wont be sad too long haha). Anyway, I dont have a problem w/the so called "lack of themeing." It's actually quite refreshing at the end of the day. I'm one of the biggest fans of Disney you will meet, but I just don't have a problem with not being overloaded with Disney themeing at the end of the day. The rooms are wonderful and some of, if not the largest on property.
You can buy your tickets on SOG property a lot cheaper and w/o taxes, just know that you have to have the tickets activated at the guest relations office of the park you first go to before they will work in the turnstiles.
As far as transportation. Know that to get there from the airport you either have to rent a car, have a town car service pick you up/drop you off on way back to airport when you leave, or if you are driving, that the parking is 5$ a day to park in the SOG garage. It's 15$ a day if you want to drive to the parks and not take a bus or other transportation.
We usually walk to the Polynesian and take the monorail or buses from there, You can also go to the front of the resort from 9am-5pm daily and ask the bellhops to take the "shady shuttle" it's a little golf cart that will drive you to the end of the property and then you just have to walk across the street to the Poly and hop the monorail.
As far as the Shades of Green buses, I've never really had a problem with them other than the fact that at the end of the night you have to know what time the last bus is from certain parks or you are pretty much stranded as monorails etc stop running. We normally didnt have an issue with hopping the SOG buses to the TTC to catch a bus to DHS. Just know that you have to take monorail to MK and EPCOT and then get back to TTC to catch the SOG bus. The one bus I will not get on is the direct AK or DTD buses from SOG because I think it only comes like once an hour or something. I would rather just go over to the Polynesian and catch their bus there.
I've eaten there before and never really had a problem although it's not the greatest food (at least not DISNEY quality). The pizzas and stuff are good at the Evergreen pool bar and grille for like after hours and stuff. (if you are going to go after dark make sure you walk there through the hotel and not on the outside paths, as when we were last there in Aug the staff told us NOT to go on outside paths at night bc of venomous snakes and gators lol).
Other than that, I can't think of anything else. If you have any questions, feel free to drop me a message in my inbox here.
