Sheraton Vistana Diamond Check In Question

[Mven]

How early in advance can we or should we sign up for this on their website???? Help

I don't think there's a limit. They want at least a minimum of 3 days advance notice. My stay there is 8 weeks away and I haven't filled it out yet. Most likely I'll do it a week or two prior to arrival.
Good luck and have a nice stay
