I was diagnosed with celiac in 2011, and our travel agent always makes sure that my restrictions are noted on all my travel reservations. My best experiences have been on Oceania Marina cruises. I have been on 2 since my diagnosis - one 35-day re-positioning cruise from Europe and around South America in 2012 and an 18-day cruise in the South Pacific in 2014. On both cruises my gluten free needs were conscientiously and courteously met by every staff member involved. Each day I was given the menu a day in advance for my chosen dining venue from among 5 restaurants, made my choice for each course, and submitted it to the dining room reservation desk. The chef and kitchen staff then made all necessary accommodations for my dinner the following day. At each meal, the restaurant manager checked with me. On a private kitchen tour, I was shown how special diet needs are handled; cross-contamination is avoided - a very impressive operation! Additionally, the restaurant staff, which rotated to the buffet and through all restaurants, were helpful at breakfast and lunch to make sure there was no gluten problem in my choices, and the wait staff, many of whom had served me at dinner, were quick to come to my assistance in the buffet, if I had any questions. There were no lapses on either cruise, and I am sure my experience is replicated on all Oceania cruises. I cannot recommend the cruise line more highly. It has been a great relief to know that I don't have to worry about gluten and can relax and enjoy my vacation whenever I cruise with Oceania.
