My FI and I will be having our wedding over a weekend in the Hamptons. Would it be appropriate to ask our guests (about 50) to pay a small amount ($50 - $75) to reserve their rooms? If so, do I mention that on my save the dates or invitations...and how do I word it? My reasoning is that if we were getting married at another destination location, they'd be paying much more than that for a weekend; plus it will confirm who's coming and how many we have to plan for.
