You'll have a great time on Enchantment. She's a great ship.
Royal Caribbean will start letting people board at around 11:30am, and you must be onboard by about 4:00pm. Leave time for possible lines of people waiting to check in.
You can speed up the embarkation process by printing out a SetSail pass. You'll need your booking number to do this. You can then go to Royal Caribbean's web site, www.rccl.com,
click on "Before You Board" and then on "Online Check-in" and then follow all the prompts to enter all the information they need.
