I got a code from a friend who works at Royal, and I wanted to confirm that putting a code to check a price (and not book the cruise yet) will not burn the code so I can’t use it when I am ready to book.
I live in Ft Lauderdale and I am a big fan of renting from Sixt. There are usually coupons and they have nicer cars for decent prices. It is pretty close to the port too.
