Thailand Capsule Hotel (sleeping in the Bangkok airport)

We flew from Myanmar to Bangkok on our way to Bangladesh and spent a 13-hour overnight layover at the airport. We checked into a futuristic capsule hotel in the airport basement, explored its lockers, bed, controls, and amenities, and compared it with our previous capsule-hotel experience in Japan. We slept well, then had breakfast and ice cream in an airport lounge before continuing our journey.
