Yes, it's advisable to extend if you are planning to stay over your 60 days and go a few days before the 60 days expires..

The extension is just added onto your initial 60 days anyway..

But some immigration offices get very busy so go soon and go early in the day

I could fly to Thailand at a moments notice with only the clothes I am wearing and it wouldn't bother me at all.

I know I can easily get everything I need quite cheap in just a couple of hours

25 to 30 hours of bus travel..

Head to the nearest bus station would be my advice

I can only offer my personal experiences and never had a problem after several trips to Cambodia including Phnom Penh, Siem Reap and Sihanoukville..

In fact after more than 30 trips through SE Asia in over 20+ years the only thing I ever lost was a phone once in Bangkok years ago which was completely my own fault anyway..

I would take far less notice of the reviews which tend to attract mostly people who have something to complain about and just focus on your own instincts and common sense.. 😁

@Bart *************

Sounds like you are being a little paranoid in my opinion..

I have been to Cambodia and Phnom Penh several times and never had any problems with theft ..

You just need to use some common sense and don't offer easy opportunities for pick pockets or leave your personal items laying around the same as you do anywhere you travel and especially in SE Asia..

Don't get very drunk or drugged and leave yourself as an easy target is also a good idea.

If you cannot manage basic things like that then perhaps Cambodia isn't the place for you.

Your visa status for Thailand has nothing to do with entry requirements for Japan..

It's your passport country and what entry requirements and visa apply to your passport that matters.

It's an interesting city and has quite a bit nightlife and bars if that interests you..

Also quite good value for money accommodation..

Stay close to the Riverfront area and enjoy 😉

If you go to Cambodia then spend a few days in Phnom Penh and have a look around..

Well worth a visit

I am always in amazement at how much luggage people want to drag around SE Asia..

Traveling light with the bare minimum makes life so much easier and more convenient..

And there is absolutely nothing you could possibly need that you cannot buy as you go should you need anything..

There are cheap laundry services available everywhere in the main tourist areas..

This is not a criticism but rather an observation and experience gained from dozens of trips all over SE Asia for many years..

It's not that difficult to travel light with the bare minimum if you are determined to do that..

Having said that..

If you have a reservation at a hotel for your return to Bangkok then often the hotel will store your bags while you are gone (assuming you are not going away for weeks at a time)

I don't have anything against Singapore itself except it's very extensive in comparison to other Asian countries and it's probably the most "un-Asian experience in SE Asia..

If that's what appeals to you then that's fine and enjoy..

I am just pointing out my personal observation from many year's of traveling all over SE Asia
