I love one bag travel, but unfortunately I have too many one bag hobbies that takes up their own bag or suitcase per hobby. Photography, scuba diving, etc.
If I want to leave things behind on long trips, short term luggage storage can get pricey. Security could be a concern with expensive equipment.
I had some success renting a long term storage for a SEA trip. I rented a monthly storage in Hong Kong and used HK as a hub. I reconfigure my packing depending on the trip. Scuba for Philippines, photo for Cambodia, one bag for urban destinations etc.
The degree of difficulties to rent monthly locker in HK is high. They require HKID, local address and bank account. Luckily I have the ID, can use relative’s address. They waived the banking requirement after dinner negotiation. But the deposit refund must go to a bank. So I gifted that to a relative. The storage outfit is one of many chains that operates in industrial parks. Have 24hr access and easily accessible via subway is key.
Overall, this is cheaper, safer and more convenient than short term luggage storage or airline baggage fees. Assuming the first and last leg are international flights with more reasonable baggage limit.
Do you have a similar travel hack? I would love to learn if there is a better approach with less degree of difficulties or cost. I think HK and Bangkok are my top options as travel hub for ease of entry and exit with a US passport.
