Ask for what you need. If you have a life-threatening allergy, tell the check-in clerk so he or she can put it on your file. Also double check that if you asked for a room with a kitchen, that’s what you’re getting. If you’re not sure where the closest medical facilities are, ask for that information as well.
Wipe down surfaces. Don’t assume that the cleaning staff have done a stellar job. Make sure to wipe down counters, tables, phones, TV converters, faucets, etc. to avoid accidental contact with traces of the food you’re allergic to.
Call ahead. If you eat at the hotel restaurant or order room service, call ahead and tell them about your dietary restrictions. Many hotels are accustomed to dealing with allergic travelers, and can accommodate your needs. If they can’t, don’t risk it – hit the local market and whip up a stellar, and safe, meal.
Talk to the concierge. If you stay at a hotel that has a concierge, tell him or her about your allergies and ask what resources are available in the hotel and surrounding area. It may be that there’s an allergy-friendly restaurant, bakery or shop just around the corner.
