I haven't really looked into this properly yet but I just stumbled across a site that was offering angkor wat tours from ko chang. They all seemed to be at least 3 days and anything up to £500 per person which seems extortionate to me.
I am aware that I clearly won't know what I'm looking at without a guide but can you just walk around on your own? I'm quite prepared to just be blown away by it without knowing all the finer details. Perhaps naively I had only planned on 2-3 nights in siem reap due to time constraint and hadn't really considered having to budget for it in this way.
Probably rather stupidly, I had visions of arriving in siem reap, finding a hotel, going to the ruins and having a wander round for the day and leaving on the third day. Is this at all possible or have I completely misunderstood how it all works up there?!
Sorry for my ignorance!
