There is a left luggage storage room at Suvarnabhumi Airport but if you leave something there for 2 months it is going to cost more than using a hotel with free storage or cheap storage.

I used the Sukhumvit Crown Hotel off Sukhumvit between Soi 6 and 8 to store bags for me. They used to have a storeroom behind the front desk. Haven't used that place in years but they never charged me for bag storage. I would leave a bag there and come back a couple months later and retrieve it. I feel you are obligated to spend at least the first night and last night with them. They have an "all you can eat" breakfast buffet. From the Nana Skytrain stop you can see the Crown, it is the brick building behind the never completed construction project. Do the math on what it costs to store something.

If you intended to store winter clothing you could try flying with less bulky winter items or give you heavy stuff to whoever drives you to the airport. On the return you can just layer up with extra shirts and a thin zipper jacket. I once used socks on my hands when I forgot a pair of gloves for my walk home through snow on my annual trek back to the old hometown!

Good luck.

Fabulous if you can get somewhere to store it for free, if not New Joe Guesthouse (just off Khaosan Road in Banglamphu - Google it for their web site) will store for 8 baht per item for guests or 10 baht per item if you're not staying there, all fees per day. Works out pretty good value for money. As others have said, I wouldn't leave anything ridiculously valuable, but I have never had anything go missing from there, and it all comes back in the same condition as it went in, albeit a little dustier. Good luck!
