BlueTravel

Family of 8 traveling for first time on a Transatlantic. Diamonds for the first time as well. Anyone that has sailed on Odyssey before, is it easy to plug an HDMI adaptor from TV and/or do their TVs have the button on the bottom of the screen for source options? Does anyone know how does the schedule on ship change daily? I believe clocks move every day and 23 hr days? I wonder how full is this cruise - expect to see a few kids only since it is still in the middle of the school year. Thanks!
