We are having a wedding of about 250 invited guests in the town where we live that happens to be about 4 hours away from where my family and many of my friends live. My FMIL has graciously agreed to host a welcome dinner for the 175 or so of the out of town guests- almost 2/3rds of these guests are my friends/family. I greatly appreciate her generosity, but I think it may be a bit overboard. My father is worried that his family, many of whom struggle financially, will feel the need to spend money on the hotel room for a 2nd night if they are invited. They could easily drive down the day of the wedding as our ceremony starts at 5 pm. I personally just think that 150 + guests the night before my wedding will be a lot for us to handle. At the same time, I certainly understand that my FMIL wants to host her own family and out of town friends (and of course the bridal party and my immediate family) that night, which is a much smaller number- like 65.
Would it be appropriate to ask that she just invite the bridal party, my immediate family, and whoever from their side that they wish to invite? Or is this rude to my friends and family who may have come down the night before?
