"It's often a good idea to keep your picnic under the radar."
This is the best advice.
Some hotels have a no-food-in-room policy for important reasons. I know one hotel in Italy that is famous for its nearby bird sanctuary. Their rooms offer outdoor terraces, and food can create a nightmare for them. They do their best to control the situation so that all their guests can enjoy the views.
I eat when I'm hungry, and that means often, because I'm a very active visitor. I ignore certain rules that conflict with my personal and professional needs. Certain rules are for people who lack discretion and consideration of others.
It is quite normal for me to be awake at 4:30 AM in Europe, especially the first three days. If I am up that early, I eat two breakfasts. I travel with my own homemade granola, high-quality oatmeal, chopped roasted pecans, and fresh-roasted ground coffee. A high fiber and high protein diet is crucial for my good health, not always easy to find at odd hours in Europe.
I travel with a miniature kitchen. My luggage list always includes:
- special travel bowls for food
- travel cups for beverage
- Nalgene bottles for olive oil, balsamic vinegar, and liqueur
- tiny travel jars for spices (sea salt, fresh ground pepper, sugar, cinnamon, nutmeg, herbes de Provence, vanilla extract)
- travel Melitta with coffee filters
- travel utensils
- immersion heating element
If I'm up early and eat two breakfasts, I can put off lunch until 1 PM, which is normal for locals but not normal for me. I often eat lunch with a local. If I eat lunch between 1-3, then I can do a light dinner between 8-9:30. Sometimes I nap between 3-4. I try to be in bed by Midnight, sometimes by 11 PM.
I have never been a carry-on only traveler. I could never function happily with such restriction. I don't require a lot of luggage space for the items listed above. After thirty-plus years, I happen to be an expert packer. One of my bags is a backpack, and no hotel has ever asked to search mine before going to my room. I have enjoyed a vast array of goodies through the years, in my room or on my terrace. For me, food is very much connected to my joy of travel.
