Given a travel related situation, and given a specific question about the situation, summarize the question into a title

Ex Input:
I'm travelling from Munich to Bangkok via Muscat at the end of September (economy class, so no lounge available). The Airport in which I'll land will be the Suvarnabhumi International Airport and the local time will be 8.00.

My parents will be flying with a different plane, which will land at the same airport at 13.00.
Provided that we already reserved our hotel in BKK and I asked if I could do an early check-in, to which they replied that I had to pay a night more (didn't expect that from a 5 stars hotel), I see myself bored as hell, sweat-stinky (apparently there's no possibility to take a shower in that airport), waiting on a bench with all my (heavy) stuff around. I would very much like to avoid that.
What are my best options (money/time/relax-wise)?

Could I do anything decent enough to spend a couple of hours in the airport (possibly having my baggage stored anywhere?
Should I go to the hotel and try to see if they can make me check-in anyway (and try not to pay more)?
Should I surrender to the hotel's policy and have my room ready for me by paying a night more?
Should I go to the hotel, store my things and go out strolling a bit (with jet-lag, without shower and so on...)?

Ex Output:
5 Hours (at least) to spend in BKK Suvarnabhumi or what else?

Ex Input:
I live in Canada with a German passport and a student visa. From a recent climbing trip to the US I still have this green I94-W form in my passport. I didn't surrender it on leaving the US back to Canada, because I expected to come back for another climbing trip relatively soon.

That trip got postponed a few times, and now the situation is that the I94-W would expire while I'm on the trip. That is, it would still be valid on entry, but not on exit.

Can I apply for a new I94-W at the border crossing, or can these Visa waivers not be extended back-to-back?

Ex Output:
Extending an expiring I-94W, land based entry to US

I am going on holiday to India for 6 days and was wondering if anyone knew of any form of preventative medication which I would be able to acquire in order to try and stop some myself getting some of the local bugs.
