Really depends on what’s most important to you. Getting to the parks is equally inconvenient.
For me personally, I love the tranquility of OKW and the bigger rooms. Last time we stayed at OKW in building 25 and our unit overlooked the 5th green from the golf course and it really added to the vacation away from the vacation feel. And I really enjoy the boat ride down into Disney Springs. So for me I would do OKW in a heartbeat.
But for easy access food options, hands down it’s SSR. At OKW your only real option is Olivia’s. If you’re hangry, waiting for the OKW boat just to get dinner at Disney Springs isn’t much of an option. And as mentioned above, there is no spa at OKW.
Finally, on the pool front, I have a 5 year old, so the main pool at OKW worked for him (and especially since we were super close to the Hospitality House). We didn’t get over to any of the other OKW pools, so I can’t comment on those. Anyway, if using the main pool at OKW is a major draw for you, not getting a unit close to Hospitality House will be a major drawback.
