Out Of Town Guest Dinner vs Rehersal Dinner

Who to invite.......

Our ceremony is at the Westbury Manor so we really don't need a 'rehearsal Dinner' but we will be having a lot of out of town guests and would like to do a dinner for them the night before. My question is should I invite only the Out Of Town Guests and not the bridal party? Or should I invite the bridal party?

I am open to all suggestions.
