Lots of great info here regarding BKK transfers but my specific question hasn't been answered, at least not that I can see.

I'll be arriving BKK around midnight from the States via NRT. I am departing on a Bangkok Airways flight around 8am for HKT. My plan was to stay in the allegedly overpriced transit hotel however after booking my PG ticket, I'm wondering if this will be possible?

Their website leads me to believe only through checked passengers can remain airside and not have to go through passport control etc. I was planning on being one of those types, by using the web check in. It seems though, that web check-in customers must present themselves at the "web check in counter" in the check-in lobby, which then forces the transit passenger to exit the airside area and therefore unable to use the transit facilities.

Am I interpreting this correct? Perhaps I should just book into a close by hotel and give up on saving time and precious sleep hours.

Thanks!
