It assumes that we have net inward migration of 300,000 wage earners pa for the next 5 years and relies on income tax, NI and VAT receipts from their economic activity to pay for our services without excessive government borrowing.
45,000 pa come by small boat. Over the past 3 years that totals 135,000 some of whom have died, left (eg to RoI), deported or granted asylum. The other 1.1 million increase in UK population has arrived by regular means in line with government policies and laws.
depends on how many long stay guests the hotel has. The new rules most immigration offices are pushing mean anyone wanting a 30 day extension to stay on in Thailand needs a TM30 copy. Some ex-pats in condos and apartments being let by some private landlords get told stay in a hotel for the night to get the TM30 for your 90 day report.

All the advice you have been given about getting the 30 day extension to avoid an overstay is correct.
In case you don't know the first day you arrive - even if it's after 11 pm - is day one (not day 0) so the 30 days is up on what you may otherwise count as day 29 of your holiday.
