This probably isn't the right forum but I'll ask anyways....our poor TA has had to suffer through A LOT of changes for us to finally be able to cruise (close, but not there yet). Constant change, book, re-book, cancel, add, drop, etc. With most everything done through email and a few phone calls (we have never met face to face), what's the best way to send a thankyou? I don't feel comfortable asking for a physical address. What's considered proper?
