Use BTS, not taxis.
Bangkok traffic is legendary. The BTS Skytrain is elevated, air-conditioned, and runs above the gridlock. Get a Rabbit Card on arrival (100 THB deposit, top up as you go) - works on both BTS and MRT. Day pass 140 THB if you'll do 4+ rides. Grab when there's no BTS nearby; taxis only if both fail.
