I'm planning on going to Thailand in October and back home for christmas. For various practical reasons, the most convenient dates for travelling mean that I would spend about 70 days in Thailand. The thought of standing in line at immigration and paying 2000 baht for an extension which I will only use 1/3 of doesn't seem that appealing... are there any better/cheaper alternatives when only staying slightly more than 60 days? Thought I've seen something about a 7 day extension somewhere?

All extensions costs the same, 1900 baht.

Only alternative you have is to make it to the border and re-enter.

As above:

I am afraid there is no better way than visiting the immigration office and pay the 1900 for a 30 day extension (I assume you travel on a tourist visa and do not qualify for a Non-O).

The 7 day extension is not cheaper/easier and would not gap the 10 days.

 

And a border run in high season?

Sure not convenient/cheap.

There is no 7 day extension. Immigration give people 7 days to leave the country that don't qualify for an extension of stay or have an extension application refused. As you would qualify for a 30 day extension thats what they would give you for your 1,900 baht.

 

Unless you're staying very close to a border crossing getting an extension is your best option and almost certainly the cheapest.
