This will be our first time sailing and I'm SUPER EXCITED and I can't wait!!

I booked it for my twins' surprise 16th birthday.


Just need to be pointed in the right direction as far as FE groups and all things a newbie should know.
Also, is there any other place to join and see things on the FE group? I want to keep this a SUPER SECRET SURPRISE and if I join the FB group, our family members would know.
