I’m lactose intolerant and I’ve been on 12 ABDs. I always note my intolerance with
ABD and they do their best to accommodate my intolerance at group meals that are done by ABD. However, as they mention, they can’t always guarantee that the place that is serving the meal can provide an alternative meal. Having said that, I’ve never gone hungry on an ABD. To date, I’ve traveled to Egypt, Ecuador, Galapagos, Italy, Greece, Australia, New Zealand, and other places with ABD with my intolerance. I may have had to eat something I didn’t want, like always having fruit for dessert because everything else had dairy in it. If it’s a buffet, they will ask the chef to walk the line with you to let you know what you can safely eat. If it’s a plated dinner, the restaurant is told in advance that a special meal is needed and you sometimes select your meal in advance. When I did the Galapagos trip, it was interesting that they would make a special boxed lunch for me (on the days we had them) that actually had cheese in it—even though they said it was lactose free. Of course I didn’t eat it—I take lactaid if I know dairy is in something, but I’m not always sure and hate to waste pills. Sometimes even with the pills, I still get sick.
The guides will give out snacks during the trip. I would ask the local guide to point out the safe snacks that your children can eat so that they know what to take when the snack bag comes around. I’ve also seen other parents of children with allergies bring their own snacks from home.
I know an intolerance is different than an allergy, but wanted to share my experience. For the meals you do OYO, the local guide can write a message in the local language to show the waiter so that they know of the allergy. I would err on the side of caution and scrutinize everything that your child is served. The kids normally hang together and can also provide support. As I’m sure you do, make sure your child has their Epipen on them at all times. There was an incident on our ABD Danube River Cruise where one of the kids who had a nut allergy got a danish from a local vendor not realizing that it had nuts. He had a reaction, but thankfully the other kids in the group were able to get help and one of the people on the ABD was a doctor who assisted him. If you haven’t already, I would suggest doing your own research to see how prevalent peanuts/nuts are in Peruvian cooking. ABD will do their best, but since they’re not cooking the food like they would at most Disney restaurants, they can’t guarantee anything. Hopefully, someone with this particular allergy who has been on the trip will post.
