In thinking about this, I am now wondering something completely new (but still on topic)!
We tend to stay at a moderate the night before our Sunday check in. This next trip, we are staying at POR and I plan to run over to SSR early to "check in" for our GV and 1 bdrm. Would anything be gained (or would CM get irritated) if I went over on Sat and nicely asked if there was more than one GV available for Sun check in with our request? If there was only one, then there would be no reason to head over there early, likewise there would be no getting my hopes up if our request wasn't even going to be available. I only consider this, since GV aren't very common... If the CM said, "No, all of the GV will be available tomorrow as everyone is moving out on Sun (unlikely with the high points on weekends and the fact this is Jan we're talking about) I'd make sure to get there really early.
OR...Due to the fact that we've linked the GV with the 1bdrm through Grand Gatherings, is it more likely they will be completely preassigned and it won't matter when I go over in the morning? Guess it won't hurt me to go Sun am, more than anything I'm just curious about what you think about the process, the other thing is that I'm trying to get into the GV early enough to get everyone ready for dinner and a Magical Fireworks cruise, wondering if that's even possible.
