We were at SSR in June and again in October and got wake up calls every morning and afternoon and usually at a time we were all awake. They were always Stitch. I didn't even think to request an odd time, we'll try that in March.
Just got back from OKW and SSR. Both resorts had Stitch screaming in our ears. It was SOOO loud, you couldn't really even tell it was Stitch...let alone hear the message.
We stayed at POR several years ago and got the cutest wake up call from He said "Up and at 'em" I still say that today!
