lol - I can totally relate!!! John's mother (very many horror stories here) told us she was booked at French Quarter (booked this 2 weeks prior to the wedding when she'd known for a year and a half but that's another story

). So when we went there to meet her, we found that she was booked at Riverside which was where we were

Fortunately her flight was delayed, so we had enough time to go to Riverside's front desk to leave a message for her. And since it was the night before the wedding I had a bridal moment and started crying. The wonderful CM at the front desk showed us where they were supposed to be (next building to ours), and when they actually checked in they were at the other side of Riverside
Before the wedding we had made it clear that our honeymoon started after the wedding was over, we would be there a few days prior to the wedding and would be more than thrilled to visit then. His mother was very understanding about this and didn't attempt to see us after the wedding. We felt a little bad about it, but it was her decision to arrive late the night before the wedding.
It's not selfish at all of you to want your honeymoon to be just that - your honeymoon, not you entertaining everyone. Don't feel bad at all. You have set aside days for family and friends, just let them know that. If they don't take the hint, don't tell them your room # and don't answer the phone

The CM at the front desk on that night told us how many mothers call to speak to their daughters on their honeymoon, and she has to forward the messages, they can't give out the room or phone #. Besides after all the wedding stress, you two need a chance to be alone and just relax!!!!!!!!!
Good luck
