Overnight stay near main highway

Hi all,

Am driving from chaiyaphum on Wednesday and want to stop a couple of nights somewhere where I can easily park just off the highway.

I hate driving in the middle of the city cause of traffic and gps sometimes <deleted> up. Last time I attempted took a wrong turn and had to flag a taxi and follow it.

So normally I leave car at airport parking and use taxis or underground.

Wondering if there's an easier way.

Ta
