Hi all
I’ve always received good travel advice from here.
The wife and I are going on an organised tour of Cambodia, Vietnam and Thailand next month - 21 days in total. It’s the first time we’ve been to SE Asia and our first experience of a long tour.
Trying to find out about practicalities such as handling travel money in 3 different currencies , using mobile phones (eSIM the best option?) what to pack and laundry ( I don’t fancy lugging 3 weeks worth of clothes around!), essential vaccinations, any lingering Covid issues etc but really any tips and advice much appreciated.

Thanks in advance
Casper
