I'm gluten free ( I can't eat wheat, barley, or rye) and egg free. It can be kinda hard to find places that I can eat and accidental contamination could ruin the trip.
I have been on a cruise and the food was great and worked well for my diet. However, FI is worried that the food will be too good and won't help his weight loss goal.
I have heard Disney is good with allergies but we would prefer to save that trip for a vacation when we have kids.
Mexican food is normally pretty safe but neither of us speak Spanish so it might be a little more difficult.
