haha. well this will be my 16th Thailand visit. I have visited most of the attractions. However there are reasons for this itinerary as you say. One is i found a cheap ticket to Bangkok and then again a cheap ticket for Bali from Bangkok. My original plan was Bali but everything considered (ticket, visa, re-entry) i'm paying about 300USD less if i wanted to go straight to Bali. The other reason is i want to meet a friend in Thailand and i have his birthday present with me.
Anyway thanks for replies. I think this issue is solved.
