Over the last few years my wife has developed, or determined that she has some significant food allergies. We are able to eat well and healthily at home thanks to research, trial-and-error, and not eating out, except for a local Thai place that we get take-out from about once per month. Travel is more of a challenge.
These aren't anaphylactic-level allergies and insensitivites, but they are bad enough to ruin the following day - not something we want if we're on a two or three week trip, especially on days when we might be changing location, although we would like plan on only two or three location changes.
Over the last few years we haven't travelled a ton, but when we do we try to locate ourselves somewhere we can do our own cooking. Airbnbs have worked well for us, but in our area they are being regulated almost out of existence. I support that due to the incredibly low vacancy rates and extreme house prices in our area since it's bad for our society overall, even though it make our local travel situation more challenging as hotels with full kitchens aren't as common or pleasant. Restaurant meals are doable, and most do a really good job of dealing well with allergies, but it's still a gamble and takes a lot of the fun and spontaneity out of travel. We've had relatively few problems with restaurant meals in Canada and the US, but adding a language barrier might add to the challenge. For travel to see family this Christmas my wife dehydrated a bunch of meals to bring with her just in case, but that's less of an option for a longer international trip.
I've travelled fairly extensively and still prefer the train pass, backpack, and hostel approach when alone, but I'd like to plan a family trip for March Break 2025 to Amsterdam, Berlin and Munich that allows us to avoid food allergy issues without meal-planning dominating the trip, and without having to carry much so we can travel lightly. The three-city itinerary is based on flights always seeming cheaper into Amsterdam so I'd like to start there, and since I haven't really been since 1984 I'd like to check it out again... Berlin has been on my list for a long time but I never made it despite spending almost a year on the continent post-Berlin Wall. And I have friends in Munich that I would like to visit. Alternatively, I also have a friend in Grenoble I would like to visit, but keeping the moving around to a minimum seems like an important part of this plan.
So, does anyone have any advice or suggestions for traveling to these cities with the allergies/sensitivities listed below, in terms of where to stay, shop, and eat in order to make meal planning fade mostly into the background?
Gluten - not diagnosed celiac, but assume that's what it is
Lactose (wife) - lactose-free milk and cheese has been fine
Whey (son) - all milk products seem to be a problem, but not as severe as any of my wife's allergies
Grapes - including raisins and wine
Chickpeas
Pea protein (maybe)
Aside: I feel like if you showed up at customs to enter France or Italy they would reject you if you couldn't eat bread/pasta, cheese, and wine.
Given how many of these ingredients hide (wheat is in soy and other sauces, acquafaba (chickpea water) in desserts, etc.), combined with different approaches to food labeling, I'm wondering how well we would do in grocery stores let alone restaurants. Any advice here would be welcome.
Specific questions for both The Netherlands and Germany:
1. How easy is it to get reasonably-priced accommodation for 4-7 days that includes a functional kitchen so we could cook our own meals?
2. What's the general availability of foods labeled well enough that we could find dairy and gluten-free options to cook?
3. How well do restaurants handle food allergies (and how to best communicate the specifics)?
I speak French so maybe we should go to France instead, but I also lived in France and can totally see a lack of willingness to accommodate these restrictions...
