Hi Rob, do you enjoy reading? I could never travel without a good book. Yes, you will be able to watch a movie or two on board. I try to read a little, sleep if possible and have the occasional walk up and down the aisles to stretch your limbs from time to time. Drinking plenty of fluids, water or juice helps stop you becoming too dehydrated. I'm sure you will be fine in Bangkok. Have a great time and don't work too hard!
