Upon arrival at the airport in Bangkok what's better go to the cab stand or order a grab ride?

Late night airport taxi.

(I have this problem all the time.)

We booked taxi from Bangkok city center to airport at 4am, but i am worried if he actually arrive in time.

So in any case of emergency:

1. Do Grabs works well in midnight?

2. Any popular taxi company that work all night and is reliable and that i can call to in such case?

Thanks.

Hi I will have a 10 hour layover in Bangkok, is it possible to leave the airport and go to the city for awhile then back again? Like a normal tourist but for a short while. I ask because I saw on quantas website that transiting between international flights, it is not allowed.

Hello, please I don't know if I must book the transportation from airport to hôtel of if I can go there by myself whith public transportation ?

I have seen 2 prices for the PCR test, one quick and one " normal", cheapper ; is this one quick enough to be able to leave the hôtel after one night ? Generaly, you are supposed to leave the room at 11. So what ? You wait in the lobby ?

Thanks a lot
