My experience today:
The team kept following up with me and gave me a great service.
Taxi was 10 minutes early, came pick me up 5.50am from my place. He drove fairly safely and we arrived 9.45am.
I was warned that I may be asked to bribe immigration 1,000B since I have an extensive history here in Thailand. The lady IO was indeed complaining about my passport while turning pages. The contact from the company implied we'd give the bribe and she stamped me in quickly, no questions asked.
The border was dead empty today, which was great. I managed to get in and out in 25 minutes. Couldn't be happier.
My driver quickly finished his early lunch and we left at 10.30am as I wasn't hungry.
We arrived back at my place just before 2.30pm.
All in all, a great experience. I paid 7k, but would be 6k if you have a more normal passport history.
I hope it will help others in the future that were thinking like me from Bangkok.
Thanks everyone
