I always use a taxi to travel to/from the airport.
It’s quicker, it’s more comfortable, you don’t have to walk/ travel extra miles to your accommodation, reliable and waiting for you, no queueing, and it runs on time.
OK it costs 7 times as much (about 1300 baht) but that’s only 3/4 of the cost of short time off!
After 5,500 miles travelling I’m not going to pinch pennies on 1300 baht.
By the way the same distance in the UK would cost you about 7000 baht, so it’s no contest!
