So my future sister in law very generously offered to get us a limo for the wedding, which we had already decided against. Basically, the hotel is less than 5 minutes from the venue, so, in my opinion, it just seems really silly to get a limo for 8+ hours (we need to be at venue for 2 and reception ends at 10) for a likely total of 20 minutes driving time.
I greatly appreciate the offer, especially since his family hasn't really offered to help us with anything else financially, but it seems like such a large expense for something that's not super useful, when we could really use help financially with other necessary things. Is it rude to say "Oh we so thank you for the offer to get a limo, but since x, y, and z, we had decided not to get one. However, if you want to help with the wedding, we'd love if you could help facilitate (blank)"
Should we just accept? Decline and see if she offers something else? Or should we just be honest and give her some options of other things we could use help with?
