Hello and congratulations,
I have done a couple of weddings there...and you are correct, you will be on the bridge by the pond. Your family however will not be in the gazebo.. it is too small there. They will be standing in the walkway across from the bridge where you will be standing. It is a nice venue that offers privacy for you and your guests.
Best of luck.
I haven't been to a ceremony, but I have been to the museum...I think it would be too small for 16 people. They used to limit parties to 10. There is a winding path bordered by bushes, so views are tricky. It is really pretty, though, and the butterflies are very friendly.
My husband and I were married in Key West in March of this year. I did not get married at the museum and have not visited the museum. It sounds like from the other posts the venue may be too small. If you have any other questions feel free to email me at email@example.com
I have done several weddings there they only do them for 20 people or less so a group of 16 people is just fine. Here are some photos from my Facebook site you can look at to get an idea of what your wedding will be like.
