Yes, the $34 had included all the taxes, svc charge and breakfast. Samran is behind Asia Hotel, near to Ratchathewi BTS station. Well, i will only stay there during Oct, thus i can't answer your other questions. Thanks to AhJo77 for the answer to your queries.
Usually i take cab to my hotel place from airport as i DIY my trip to bangkok, not thru agency.
I booked SQ flight thru Zuji, the price is cheap, only $219 per pax (with the tax and surcharge). After i confirmed, i realised if you booked thru SQ website, it's ard $15 cheaper. Compared to valuair and jetstarasia, it's ard $20 more, i dun mind to spend a little more for more comfort this time round. How abt u, had u booked your flight?
