Make sure you return before the expiry date of your 60 day entry stamp OR extend for 30 days and get a re-entry permit at the same time at immigration.
Possibly the problem many times is that many people already have an answer in their head that they want to hear or that suits their plans. Often they don't accept the actual answer because it is not what they wanted OR because there is no clear answer that can be given. Will I get a visa? Will I get in to Thailand after 2.5 visa exemptions and 1.7 tourist visas. Will I need an onwards ticket? Also 90% of the people that post have NOT reviewed the pinned topics or the previous posts or gone through any of the comments, which would answer their question before posting the same question for the 50th time. And they wonder why commenting gets closed quickly ;)
