I stayed in the Nana hotel, and when I went to Pattaya I took the Deluxe Bus from the Ekamai Southern Bus Station to Pattaya for about $4.
To get there, I took the BTS monorail skytrain from the Nana Station -about 4 stops- to the Ekamai station (cost about $1).
There are busses to Pattaya all day long, from early in the morning until late evening. It cost 114 baht. about $4.
In Pattaya, the bus stops outside of central Pattaya, and there are waiting baht busses that will take you directly to your hotel for 50 baht - about $1.50, but they make many stops dropping every one off at their hotels.
I continued on to the second bus stop in Jomtien, the city about 2 miles south of pattaya on the other side of the headland.
There were waiting baht busses there also, but I was staying at a hotel near walking street, so I just grabbed a soda at the convenienc store, and then grabbed the first regular baht bus heading north, and got off near walking street at South Pattaya Road -cost 10 baht, 33 cents.
I like public transportation, and that I won't get ripped off. I don't like taxis much, and I will never take a tuktuk again. I have my tuktuk story : I was late getting back to my hotel when I had a pre-arranged barfined lady waiting for me, and the tuktuk driver turns left when I knew he was supposed to turn right. "hey what are you doing!" . He replies , " Oh sorry, oh yeah.. you want to go that way.. Ummm,, You want lady? NO, You want suit? NO -You want gemshop..NO!! What a HASSEL. I barely got to my hotel on time.
