Your First Seventy-Two Hours Decide Whether the Trip Went Well
There is a sequence that works and it is not the one people follow, and the first two hours are the only time a single decision saves you a hundred dollars.
Almost everybody lands, goes to the hotel, sleeps for six hours, and starts the trip the following morning in a city they have never seen with no local SIM and no idea where anything is. Three days are gone and they have visited a room.
It does not have to go like that. Here is the sequence that works.

The first two hours decide the money
On the plane, before you land, buy or arrange the local SIM. Airport prices are higher and the counter queue is the longest thing you will do all day, and a working phone is the thing that turns the next two hours from a problem into a task.
Then get cash before you leave the terminal, at a bank counter or an official exchange rather than the first exchange booth you see, and get more than you think you need for the first three days because everything works better when you are not counting notes.
And photograph the taxi or ride-hailing receipt, the ATM location, and the first day's transport. None of this matters until one of these goes wrong, at which point it matters enormously.
The arrival itself
Immigration is the queue and the queue is the thing. Have your documents out before you reach the counter, because the person behind you is in the same queue.
Customs is two channels and you have written the allowances, and walking the green channel with something over the line is a fine and not a gamble.
And the arrival card question set is short and predictable, and the answers that cause problems are the ones people improvise. Answer plainly, answer consistently with your accommodation, and do not volunteer anything.
Getting from the airport, which is where people lose money
Know the legitimate options before you are in the arrivals hall, because the people offering help with your luggage are not volunteers.
The airport rail link and the airport bus are both real, both cheap, and both run on a schedule you can look up on your phone in the taxi, and the rail link is the answer for almost everybody in Bangkok unless you have four people and six bags.
A booked ride-hailing car is the answer for a family, for late arrivals, and for the island airports where the public transport is a songthaew.
And the single rule: decide the transport before you pick up the phone to a stranger offering to help, because after the phone conversation you are negotiating and you are tired.
Day one should be boring on purpose
Do not build a day of sightseeing on the day you land. The heat, the jet lag and the unfamiliar scale will make you resent it, and this is the most common way a good trip starts badly.
What to do on day one: a bank or ATM, a real meal somewhere local and cheap, a walk around your own neighbourhood, and finding the two things you will need at two in the morning.
Which is the part people skip and which is the part that matters, because the difference between knowing where the nearest pharmacy, the nearest laundry and the nearest night market are is the difference between a good night and a bad one.
Day two is for the transport mistake
Nearly every first-time mistake in this country is a transport mistake and nearly all of them happen on day two when people are tired and confident.
So day two is the day to get the airport rail line or the bus terminal figured out, to set up the ride-hailing app, to establish how you will actually move around, and to buy a local SIM backup if you only have one network.
Not the sights. The logistics. The sights will still be there and the logistics are the thing that determines whether you enjoy them.
What to deliberately not do yet
Do not buy a motorbike on day two, do not sign a long lease on day three, and do not commit to a long-stay visa route before you have been somewhere else in the country and come back.
All three are decisions that feel urgent on day two and feel obviously correct on day thirty, and the cost of getting them wrong is much higher than the cost of waiting a week.
Which is the whole thesis of the first three days: settle the infrastructure, not the itinerary. Everything interesting is still available on day four, and a good setup makes the rest of the trip easy.
