hi brenda,
i planned them before i got down there. i wanted to make sure i had a tour with prices nailed down with transportation figured out.
what i did was put a page on my website with info on the different events, price, etc. and asking people to RSVP for certain events.
i had deep sea fishing, spa day for ladies, snorkel/sailing trip, brunch with the newlyweds.
some of the events were pretty loose in terms of have RSVP (brunch with newlyweds) but some were more strict with RSVPs like deep sea fishing (we needed to reserve the right size boats.)
hope this helps.
tammy
