The Ratchathewi (N1) Station is linked with covered walkway to Asia Hotel.
I take from this station downwards direct to Asok Station (E4). (There is a interchange at Siam Chit Station near Siam Square.)

You must alight at Asok Station and went downstair to change to Sukhumvit Skytrain Line and the station to your destination are as follows:

7. Sukhumit
8. Petchaburi
9. Rama 9 (Phra Rama)
10. Thai Cultural Center
11 Huai Khuang ----------alight here for massage outlets (as per my list)
12 Suthisam ------------alight here if you want to go to Poseidon
(Note: the No. 7 to 12 are Sukhumvit Skytrain Line station no.)

From Asia Hotel to Asok Station is 8 min and the fare is 25 Baht.
The whole journey cost less than 70 baht (less than $3) and takes about
15 to 20 mins.

That's all for update now......................to continue.
