Bhai, I travel to Thailand frequently. I suggest you to make plans for 2021 because this year is almost gone now in lockdown. Take direct flight to Bangkok Suvarnabhumi , visa on arrival , immigration process and 20,000 Baht per person as amount to prove that you are financially stable to depend on your own during the visit , Indian passport holders get 15 days visa, visa fees is 2,000 baht per person ... need 2 passport size photos with white background and from airport you can take bus to Pattaya will cost you around 100 -120 Baht per person ... will take 1.5- 2 hrs drive ... cab will cost you 900-1000 baht... 1 baht = 2.40 INR
