First and foremost , welcome..... glad you found us.. :grin:
As long as you have passports you guys are good to go.. no birth certificates are required!
In Key Wets Its been years since I have been there.. I am sure others will be able to help you there although I will say it is a small island and if you guys bike .. you may just want to rent a few bikes and go off on your own.... remember pink is the color of key west!
Good luck and glad your here Tbaby
