Thank you all for the advice. To give more context, we are arriving in BKK late on July 10th, heading to CNX on July 13th, then to USM until July 22nd. We arrive at BKK after 6pm and don't head back to LAX (via NRT) until 8:10am. At the moment I have a room reserved at Best Western.
I was wondering if it made sense to head into town for one last evening which would be easier from Novotel or just relax close to the airport until the next day. I'm not sure if it's worth getting a room in town for such a stay the last night. Thanks again.
