I will be traveling to Bangkok a couple of times this in June and July for business and likely will be staying over a weekend or two. I was hoping to get in some diving while there. I won't have huge amounts of time and want to avoid flying because it will further limit dive time. So I am looking for suggestions for where to dive within easy striking distance of Bangkok. Recommendations on locations as well as specific dive operations are welcome. I'd be looking for things where I could depart Bangkok Saturday morning and return by Sunday evening. Thanks in advance!
