There are buses every 30 mins or so from pataya to BKK, takes about 3 hours and a little over 100bt cost.
From there there are many easy ways to cross the border and travel the last 20km or so to Vnte (taxi, bus, tuktuk etc)
Thankyou very much for your help Bluecramp.
This is rather hard to find the direct bus from Bangkok to Friendship border crossing because of limited bus departure. I still suggest you to take bus from Bangkok to Nongkhai then take a Tuk Tuk to the border get to enter Laos at little more cost.
If you still want to take the direct bus BKK to border gate, you may spend quite much time to wait at the bus station.
Yes you can. Its called the Sabaidee bus. Book it at Khao San road. Saves time mucking about in Udon. Another alternative is the overnight train to Nong Khai, but then you will still have to take a tuk tuk to the Friendship Bridge.
I don't know what the previous poster is on about. Here is the information from "Virtual tourist."
"There are daily buses from Khao San Road directly to Laos (Vientiane) leaving in the evening, and arriving in the early morning. They are modern 2 storey buses with video, music, WC... For about 6 USD you get the transportation, border crossing guide with the group, and the dinner included.
You can book it at any guesthouse or travel agency, Nat Guest House is one of the classic ones."
Depends on how much you want to spend. friend of mine who posts on this site recommends the Vayakorn, and this place is pretty central to everything. (How much Maneki?) I have put a few people up at the Manoly Guesthouse. This place is a lovely restored French colonial mansion, has a small pool and large rooms. $30.00 per night, but about a 10 minute walk to the heart of things. Pleasant walk really.
There are cheaper places for about $10.00 a night as well.
Sorry, that should be Villa Manoly.
