No you can go over land and get your 30 day Visa on return, no problems. Good luck and have a great trip. Please be sure to tell us all how it went.

Thanks for the quick reply.

I will definitely update the forums on my experiences :)  

Hi guys,

I'll be coming to Thailand in about a month.

I was planning on doing 3 days in BKK and then go to Cambodia and Vietnam for 3 weeks and then come back to Thailand fir a full month.

Do I have ti get from Vietnam back to BKK by air in order to get the 30 day visa again? 

Thanks :)
