Bachelorette party help

So my bachelorette party is scheduled to be on June 27th. We had an original plan but then with the coronavirus it kind of got messed up. We're only doing a one-night thing. I was talking to my mom which is my MHO and she said we could all just go to a bar that's local and then just hang out there for a while and then have somebody pick us up. Not everybody in my bridal party is of age yet. My one cousin is going to be turning 21 in December. Someone else in my bridal party has suggested us to go to somebody's house and just have a big party there so then that cousin could drink. The thing is I don't know whose house we would go to. And I kind of want to experience going to a bar and having fun like that.
The person that suggested it also said that bars are too expensive and it would be just cheaper just to have it at somebody's house. The only house that I can think of we possibly could have it at is at my mom's but there's really no parking she has six dogs and she has Gates all around her house. I don't want to take the chance of somebody having to go to the bathroom tripping over gates and stepping on one of the dogs.

I just need advice. The person who is suggesting this is very outspoken.
