You totally can - but you'll have to buy a ticket the old fashioned way. The zoo closes at 4pm. Without a ticket there will be no admittance except on party business until 5pm, when guests may start arriving for the wedding.
Not at all - we just need to know in advance so that we can let our caterer know. Please make sure you communicate any dietary needs on your RSVP.
There's a question on the RSVP site (and on the RSVP cards) exactly for this very thing!
We're calling the dress code semi-formal, which to us means everything from a nice suit or evening gown to classic cocktail and business attire. You do you in terms of just how dressed up you want to get for this shindig - we just ask that you keep it classy. The wedding colors are navy blue, pale pink, and eucalyptus green - if you are partial to dressing on-theme.
Heck yes! Details TBD. There will be a password and probably a secret knock.
