Hahaha ... good memory   At a given point in time, I had a hotel umbrella waiting for me at Why Not, at CIB and at Cindy's  The clerk at the hotel was quite confused when I collected them on a night and returned all of them at the same time  But @naughtydog-bkk is right. After that I bought myself a decent one and have a girl at WN keeping it for me 

Or do what @Denbosch1971 does, borrow a decent one from the hotel and proceed to continuously leave them at CS11!

I’m biased but I like BKK year round. The only time I’m really not a fan is pretty much from now. Towards the end of December is the highest of seasons, and things get a little silly in terms of prices and how busy everything is. This period is technically high “season”, but the drop off after New Years is always remarkable. 
  They trickle in through Late November but they vanish like a fart in the wind the instant that Christmas-NYE party period finishes. 
  As for the rain… I like it. I got nowhere to be. I’ll sit and have a coffee or a beer, or get a foot massage, while I watch people struggle damply through the streets. (Word to the wise, buy a GOOD umbrella. Not some 7-11 jobbie. It makes a world of difference.)

Thanks for all information and advices, but I will go probably in middle june. It's rainy season but fuck it 

I'm probably going to try to make it over to LOS in the low season myself.  I don't mind rain terribly and I think that less crowds to deal with would be nice.  Just as long as the ladies aren't staying home.
