My wife may go to Luxembourg on a business trip this fall, although it’s not certain yet. I’m dreaming of taking a solo trip around that time. I asked AI to do a little research for me. I’d like to enjoy delicious food and spend time peacefully in places that aren’t too crowded. Day 1 Japan → Luxembourg Day 2 LuxembourgSpend time with your wife. Stroll around the old town and enjoy a wine bar. Day 3 Luxembourg → Bilbao Take an LCC or a European airline. Evening:Enjoy pintxos in the old town (Casco Viejo). Day 4 Bilbao - Around the Guggenheim Museum - Riverside walks - Bar hopping Bilbao has a slight “Osaka, but not too metropolitan” vibe. Day 5 Bilbao → San Sebastián It’s a short trip. Even just walking along the seaside after arriving would be nice. At night, enjoy pintxos in the old town. Day 6 San Sebastián “A day to do nothing.” The kind of day for: - Morning cafés - Markets - The sea - Day drinking - Bookstores Day 7 Day trip to Getaria I think this town would suit you very well. - A small fishing port town - Grilled fish - Txakoli wine - A slightly faded atmosphere That kind of vibe is wonderful there. Day 8 San Sebastián → Santander Travel along the coastline. Things become much quieter from here. Day 9 Santander - Markets - The seaside - Old bars - Cafés It feels more like everyday local life than sightseeing. Day 10 Santander → Japan
