Timeshare vacation do babies count?

So on Mother’s Day my husband bought one of those timeshare vacations from some lady while at bass pro shop I was pregnant when he bought it it’s for 4 people for 3 nights and 4 days I’m due sep 19 and we have 2 children without the baby. So with the baby we make 5 I’m really not comfortable leaving the baby with anyone in the first few months especially with breastfeeding and what not so I’m just wondering if anyone knows if they would even count the baby as an additional person as most places don’t? He doesn’t think we would be able to take her but I don’t want to go while I’m super pregnant either.
