We have 2 rooms booked under different ressies. We are now within the 10 day online check in window. would we be more likely to get rooms next to each other by checking in now rather than once we arrive. TIA for any help.
If you have requested to be near each other on both reservations, they will do their best to accommodate that request. If you didn't request it ahead of time, I don't think when or how you check in will make much difference.
