You have several options to get here

Airport Limos

2500+ bahts

Airport Taxis

1,400 bahts (all inclusive; last price we heard).

Taxi Pick-up

1,200 Bahts (All inclusive)
A clean car, reasonably good English speaking driver waits for you at the exit and takes your luggage to the car then drives you directly here, no need to worry about directions and wasting time looking for our place. You pay the driver when you arrive in Pattaya.
That's the service and price you'll get if you specify "need a taxi" on our reservation form.
We'll need your flight details to book it for you.

Airport to Pattaya Bus Service

150 bahts (last we heard)
A/C VIP bus takes you to Jomtien then a minibus takes you here.
We could not find a website for this service but if you Google "bell travel pattaya airport bus" you'll find plenty of references. Check for their latest schedule, they seem to operate only at day though.
