While the items on the ultimate packing list are the main ones that I would make sure I have, here are a few more important items to bring on top of the usual things that you would pack for a trip (i.e., toiletries, medications, electronics, etc.):
- Protein bars
never know when you'll get hungry and not have the option to eat!
- Travel First-aid Kit
with band-aids, blister band-aids, travellers diahrea med's, and things for upset stomach.
- Journal
great for writing down your memories or making notes
- Passport photos
if you are going to apply for a visa on arrival
- Earplugs - a must!
You never know when you'll have super thin walls and traffic noises start extremely early
- VPN
if you are going to do work, plan on using free Wi-Fi spots, or are needing access to certain websites then you will want a VPN as hackers use the local Wi-Fi and some websites do not work in Thailand so you'll need to spoof your location.
- Small Flashlight or Headlamp - very handy if you are travelling outside the major cities or in case of a power out
- Sleeping Bag Liner - while I have packed my items into a flat sheet from my bed to keep them somewhat dry (suitcases on tarmac's in the rain = soggy clothes), I have had friends that stay in hostels and bring their own sleeping bag liner with them to use as a thin sleeping bag when they come across questionable accommodation.
