How to send your letter
- 1
Decide who the letter is for
Writing to the hotel itself — a complaint, a compliment, a billing question, or a lost-and-found claim — goes to Guest Relations. Writing to someone staying there goes to that guest, care of the hotel, and only works while they're checked in.
- 2
Address it correctly
For the hotel: first line Guest Relations, then Nautilus Sonesta Miami Beach, then 1825 Collins Avenue, then Miami Beach FL 33139. For a guest: put the guest's full name on the first line, "c/o Nautilus Sonesta Miami Beach" on the next, the same street and city lines, and write their arrival date on the envelope so the front desk knows to hold it.

Keep it to paper, and time it
Send letters and printed documents — not cash or valuables. Mail for a guest should arrive during their stay, so post it a few days ahead; if you're not sure of the dates, call the hotel first. A hotel can't forward mail to a guest who has already checked out.
