Prepare for the Laos trip

I bought the ticket to Vang Vieng and it costs 950k VND, which is relatively high compared to a discounted flight to Bangkok, not mentioned that I need to spend a whole day on the bus and it will be tiring. To get to the Nuoc Ngam bus station at 6:00 PM, I have to go home early at 4:00 PM and then take a BRT bus and then a grab bike. If that takes me too long, then I will take the grab bike only, it might cost me 30k VND more but I don't have to wait for the bus. Things I need to prepare:

1. Passport
2. Money
3. Food: a big bottle of water and some snacks, cakes
4. Toilet paper
5. Clothes
6. And other stuffs like phone, lens,...

I got a initerary from Hang Dinh and I will find out if it has something I am looking for.
