My fiance and I are planning on having our wedding/honeymoon in the Bahamas next year. Since we are having a private ceremony consisting of only us, we have talked about maybe having a dinner for close friends and family before we leave, and a big reception for EVERYONE after we return.
The two questions I have are: 1) Do we need to send formal invites for both events? and 2) How do we send registry information without being tacky?
PLEASE HELP!!
