I am new on here, I have just found the link on a message board here in the UK.
I have cruised 5 times since I was diagnosed, and have just booked No 6 with Royal Caribbean.
I last cruised with them 2 years ago and they were very very good with my gluten free diet. I did take my own bread and crackers.
I have also done 3 cruises with P&O, their gluten free is the best (though I prefer cruising with Royal Caribbean) P&O bakes fresh rolls with each meal, soups, sauces plus they make gluten-free desserts ie Trifle, Bread & Butter pud, steamed sponge & custard etc, basically whatever you want they will do gluten-free for you. They also put gluten-free biscute in the cabin.
