Our first trip to Europe was very exciting! We had planned for months and really anticipated a wonderful adventure.We have sailed 3 times with Celebrity.This was our first experience with Royal Caribbean. Embarkation in Barcelona was a breeze! We transferred from the airport and checked in very quickly. Lunch in the Windjammer Restaurant was disappointing but our cabin was ready at 1 pm and we were delighted to be able to take a nap before the life boat drill. The Swan Lake Dining room was lovely and our waiter Wilson was very efficient. Most meals were quite good but very limited in variety.We avoided the Windjammer and had breakfast and lunch in the dining room as often as possible. We had lunch one day at Johnny Rocket's- great burgers and shakes and lots of fun, too. The Portofino restaurant was very special. We went for dinner at sunset and enjoyed sailing along the Turkish coast as well as a delicious dinner. The food and staff were both fantastic. Excursions were not as well organized as those we've done with Celebrity.The excursions were not as long as advertised. The booklet described 5 hour trips that were closer to 4 hours. The guides were excellent but rushed.The guide in Malta was so pressed for time she only allowed 10 minutes to use restrooms! There were dozens of tour buses and only 2 bathrooms! We spent 20 minutes in Mdina and everyone on the trip felt frustrated by the lack of time. The ship was only in port from 11:00am till 5p. Since the next day was a sea day, why did we need to rush? No one had any explanation. Many guests had booked two half day tours in Istanbul. The day before, we were notified that the tour had been changed to 10 hours on Sunday.The Grand Bazaar was to be a highlight but it is closed on Sunday. More very long lines at the excursion desk to make changes and find half days tours. For us, ten hours was just too long a day. The excursion staff was very patient and helpful but so many passengers had to make changes. It seemed as if Royal Caribbean should have advocated for their guests with the tour operator. Entertainment was a very mixed bag. The Beatle Maniacs were great fun, Jackie Scott was delightful, the Motown Show was terrific, the ice shows were just amazing! The Elton John show was just a disaster! We really missed the early evening music performances that Celebrity did so well. Disembarkation was fine and well organized on the ship. The parking lot was a whole different world. We sat on a full bus from 7a till 7:45a waiting for "permission" to leave for the airport!It seemed as if no one was really in charge and each time a problem developed, 6 people got together and nothing got done. As a result of this delay, the check in lines at the airport were huge! We stood in line for 2 hours and had to run to get through security to make our 10:30a flight from Barcelona to Paris. We sadly missed several amenities that Celebrity had always offered.There were no Christian religious services available on the ship.No guest lectures,no bathrobes in the rooms, no welcome glass of champagne, and a badly stocked library. I think we're "one and done" with Royal Caribbean!
