The last few days before leaving the UK were incredibly busy for us. We were desperately trying to make sure everything was sorted out in our flat before we left for our travels for the next 10 months. Travelling in your early twenties is made that much easier by not having a mortgage. Having one is a bit of a pain when you want the responsibilities off your shoulders a little bit and disappear to the other side of the world. There is A LOT of paperwork involved. Keep this in mind kids.
In the end we had to get our onward trip from Thailand booked as recent changes to the visa system means that they only grant visitors a 30 day tourist visa and you have to arrive by air and have proof of onward air journey within the 30 days as well. We agonized over this as, just as I am sure many travellers before us, we wanted to go with the flow and perhaps take a train trip to Laos at the end of the Thailand leg of our trip. But according to many sites and official advice an onward train ticket (or bus ticket, boat ticket or any other ticket for that matter) would not have been sufficient. So we bought our flights from Bangkok to Siem Reap in Cambodia, just in case. Better be safe than sorry..
