I’m traveling to visit family. I take extra epiPens and put one in a place where everyone can see it and knows where it is (like kitchen counter) and show them where the others are in my purse. If it’s my first time in that town before I go I check to see where the closest ER is.

If you’re driving, you can bring a cooler with precut or prepared foods with flatware. If you are flying, you can bring prepared foods but no liquids or knives as it won’t get through security. My daughter is allergic to tree nuts and shellfish. We usually go to Jersey Mike’s and pick up a turkey and cheese sandwich for her. I’ve baked muffins or cookies to bring too. Some places make the food go through the x-ray machine separately. So don’t be surprised if that happens to you. I also bring cookies or homemade muffins made from scratch. The best choices are dry foods that will last.

If you're going to be with family for dinner often look up brands your family uses. So you can ask ahead of time and tell them what brand is ok to use. You can also bring an allergy free dish to share with your family. I learned that's the best way for people to taste the difference and what I go through daily to find food I can eat.

Some of the higher class hotels have a person in charge of guests and can make sure to have the rooms not full of allergens. I would call and ask for guest services and see if the can help.

My son has a severe peanut allergy. We just flew to Cali to go to Disneyland and California Adventure. We used Southwest Airlines, which is pretty peanut friendly. We called ahead to make sure they knew of his allergy, and they allowed me to pre-board to wipe off his seat and tray beforehand. They do pass out pretzels that may be cross-contaminated, but I always bring food with us when we travel.
In Disneyland, we made reservations for fancier restaurants and visited ones that were less so. My son was given his own entire menu full of options that were safe for him. (My daughter is a vegetarian, and there were plenty of options for her too.) Gluten free options were available as well. If we wanted to, we could have spoken to the chef,but we felt very comfortable with the obvious care and knowledge of everyone. Honestly, we ate out three times at Disneyland! That is more often than the last year near home! It was fun to see my son digging in to milkshakes and ribs in a restaurant. ;)
We did travel to a grocery store down the street from our hotel to get snacks and such. Some things are naturally not okay for him to eat, but we had a snack bag, a fridge in our room and extra epi pens, which we thankfully did not need. ;)
Great trip!
