Trat to Pattaya 1st or 2nd Feb

[Kleyshay 0]

Hi there i will be arriving in Trat after making the border crossing from Sihanoukville to Trat vis the Koh Kong - Hat Lek crossing. I was hoping to make it to Pattaya the same day. I am leaving via boat approx midday and so i am told its 3.5 to 4 hrs plus an hour to get to Trat. Therefore I assume i'll be in Trat at about 5 o clock in the evening. Are ther any buses or mini buses going to Pattaya at this time or would anyone want to share a taxi ride (any idea of cost). Thanks
