Thanks guys! I read a bunch of posts over at CC that were conflicting about the vaccine.SOme said we wouldnt be let off the boat in Barbados without it, and some said you could pass on it, but it appears not every gets this email as indicated here, so we wont worry about it.
Its our honeymoon cruise and with all the other stuff we are spending money on for our wedding, I would hate to add something else to do or pay for! We sail out the day after!! YAY!
