Usually when i need a taxi i just go out in the street and wave for one, but now i need a bigger taxi as i have few big bags. What would be the best way to get a bigger taxi? I don't speak Thai, only English. Is there an app for texting to get a taxi or something?

If you are staying at an hotel or similar get the staff to sort it for you. Easiest way would be to stop an ordinary Taxi and get him to radio through for something a little bigger. Be prepared for the hike in rates as they may charge you for him to travel to you as well as your journey.

Go out in the street and wave for one, as usual. I have a family and do just that. They will sort you out.

You will be surprised how much luggage fits into the smallest of taxis; back seat, boot and on the roof. We have tied the boot shut with string....

Do what i do put your bags in the boot and the, back seat to.

This really must be one of the most silly posts in a while. What on earth are you carrying a Samsung double door fridge with ice maker?

I use British Airways business- that's 60kg - that can go on the back seats / boot- but who on earth wants to lug that weight around.

Otherwise get a driver with a Fortuna- you might get the fridge in?

In terms of silliness you're winning so far...

"Otherwise get a driver with a Fortuna-"

The OP knows what to do, he was asking how to get that king of vehicle, they're not the most common type of taxi.

This company is very good- I've used them a lot, they speak good english, always been on time.

Scroll down to the bottom and you'll see a variety of cars they have- you could hire a mini van if necessary.
