Rehearsal Dinner Mini Freakout

Mkay, so we're getting married on October 27, 2019, and the last thing we need to do is find a location for the rehearsal dinner (really just a dinner to get our families together. It's been 5 years since they've seen each other. And for a chance for the bridal party to meet). Unfortunately, we're not able to use the venue for that, which is a huge bummer. We were thinking of either finding a large house to rent close to the venue, or just having the rehearsal dinner at my parent's house. The issue is, that finding a large enough house is beginning to be such a pain lol. Either they're $2k for a night, or they're totally booked. And I would have no reservations about doing it at my parent's house, but it's almost 3 hours away from the venue, so we'd have to leave a bit early to get to the venue to get ready and whatnot. Should also add in here that we considered hotels, but apparently there's a huge event going on in the same town at the venue (would've been nice to know that ahead of time, but the venue's wedding coordinator conveniently left that out until it was too late to change the date), so all of the hotels are booked that night. I don't mind waking up a little early and making the drive down there, but I don't want to royally piss off my bridal party, haha. I'm trying to make this as convenient as possible. I'm sure I left a lot out, but this whole wedding planning process has me all over the place lmaooo. Hhhheeellllppppp!
