My family of 6 cruises frequently to Caribbean and more recently European ports. After achieving Diamond status last year, we decided to try Celebrity again after 14 years of focusing on our (at the time) small children. We loved Royal Caribbean but were tiring of the same menu year after year; and we had enough bruises from the Flowrider for awhile :)
Embarkation in Fort Lauderdale was easy, though we were not directed to the Elite line like we should have been and I jumped on it myself. This saved us a lot of time. Being Diamond members on Royal, Celebrity gives us the Elite status which is nice.
After a delicious lunch in the Oceanview cafe we waited for a short while until the cabin announcement was made. We waited for the attendant to open up our balconies so we three could walk up and down (but beware, you can't lock your balcony door so your companions can come in and take your chocolate!). The connecting door is actually a foyer. The good thing is that all 4 of our cards open a common front door into a foyer, then 3 feet in are the two separate doors that are now unlocked and can be propped open.
