Can someone enter Thailand, leave within 30days (i will have proof of flight out of thailand) and then come back 3months later only to leave again within the 30days?!
i.e. can you get two 30day holiday visas within a four month period???
Yes, you can. As long as you stay within the 30-day limit on each visa-on-arrival and do not stay longer than 90 days within a period of 6 months.

No Prob,...even if you overstayed for few days, the immigration will ask you to pay some amount of money for overstaying. No worries!!

Please do not condone any activity that is illegal and could get one into serious trouble.
While many people who overstayed had been asked by the immigration to just pay the fine, there have been reports (by our members here) where travellers got themselves into trouble, especially when they were found by the police to have overstayed, and were sent into police lock-up. You may say that the chances of being found out is slim, but it is still a chance, and it is a big "what-if" risk to take. The last thing you wanted to do is landing yourself into trouble with the local enforcement in a foreign country far away from home.
An update on the current state of the Thai immigration rules. It has been known for long to travellers that the rule about having to show proof of onward/return ticket at entry is seldom practised by the immigration officers. However, this seems to be not the case now. Following the accounts from several members in this and this threads, it appears that it has now become a rule rather than an exception that a visitor must present a valid onward or return ticket upon arrival at the immigration checkpoint. Failure to do so may result in denial of entry. So, get your onward or return tickets ready if you're heading to Thailand.
I have recently been to the Thai Consulate in Hull to sort out my visa and I have found that you can apply for a visa that will allow you to stay in Thailand for up to 15 months and it costs £100 basically you have to leave the country every 90 days to get another 90 day stay, you have to sort this out in the UK before you go.
That way you don't have to overstay your welcome and you're totally legal - you might end up being fleeced for a couple hundred Baht by the odd dodgy border guard, but hey not much you can do about that!!

Look at post #2 on page 1. Finland is listed (No.9) in the Tourist Visa Exemption. You will be given a 30-day Social Visit Pass upon arrival. Just make sure you have your flight to Phnom Penh confirmed. If you want to stay longer than 30 days, apply for a 60-day multiple-entry tourist visa at a Thai Embassy near you.
Good Day,
I understand from the FAQ's on the Thai Visa site..there is a possibility one will be refused entry with a 60 return ticket if one does not have a current tourist visa. Also that the visa has to have been issued within 90 of entry to Thailand.
My question is...does one have to have a visa issued from their country of citizenship.
Thank you for your time.
