Inquiry Submission By okop

Hello, we are staying at the Courtyard Marriott and are only interested in going for maybe a half day to Angkor Wat. Really just to snap a few pictures and take a little walk. Can we just grab a tuk-tuk from the street at our hotel and arrive their without a tour guide? Sorry might be a stupid question. What do we need for cash upon arrival for entry ( US cash I am assuming ) and proper dress code for myself and my wife.

I know without a doubt this has probably been mentioned on here but there are so many posts. Anything else we should be aware of?

Thanks in advance.
