I had absolutely zero issue with my gluten-free diet when I was traveling. YAY! There were two of us who were GF and two vegetarians. I believe we were all well taken care of.
The only lump in the roux was the fellow traveller who decided half way through the trip that the gluten-free options were more appealing and I watched him intercept my GF bread one morning at the hotel (God bless you, Madame Yolande, for getting me more!) and one day at lunch he snatched my baked apple with caramel out of the waitresses hands. What’s up with that?
Otherwise, it was a worry-free and completely delicious trip.
