One of my FH's groomsman recently booked his flight for the wedding for himself, his wife and young daughter. They are arriving around 9PM on the Thursday before the wedding. Best man is arriving Wednesday night. After booking his flight, I said to my FH "P (groomsman) knows that he will need to change his hotel reservation so they have a room Thursday night." FH assured me that yes, that is common sense of course. During a recent conversation FH found our that P did not book/ change his room for the night he gets here and expected us to let him stay with us. While I understand why and all; I find it rude to not even ask. Right now we live in a smaller 2 bedroom apartment that is for sure not made to have 6 people and a dog staying in it. P eventually booked his hotel for that night then asked my FH for money for the room! I'm sorry what, no we are spending a ton of money on this wedding. My FH and I are picking up P and his family that night; now for some reason they expect us to have a car seat for their child. We don't have kids, why on earth would we just have a car seat laying around for this type of occasion? And I'm not a parent as previously stated, but don't you need a booster seat or something on a flight or do airlines provide that?? Then P asked if he could just have one of our vehicles to use during the time they are here, like no we do need them. Plus my FH and I are spending the night before the wedding apart so we both need transportation. Are we being mean/ unreasonable? I should also add that the venue we booked (a hotel), rehearsal dinner and even the tux place are within walking distance of each other. Like literally they are blocks away from one another. We did this on purpose so no one would not be able to get to one place. There is also a grocery store, gas station, Subway and Culver's right next to the venue. So they shouldn't need a car, and if they did they can ask for a ride from us or another groomsman..
