You should have received one zoo ticket per invited guest in your invitations.  Please reply based on that number.  

i.e. - If you received 1 ticket, please let us know if 0 or 1 of 1 will attend.  If you received two tickets, please let us know if 0 of 2, 1 of 2, or both tickets will be used as both guests are attending, etc.

Thanks and we cannot wait to share our special day with you!!!!
