Yup, lots of space & this was probably the first time I've seen Dubai Airport rather 'quiet'. Reminds me of a mall too. They've also opted for floor tiles than carpet ~ sneaky, as to discourage passengers aka 'airport refugees' from sleeping on the floor. It was freezing in the terminal as well.
The J lounge is also much, much bigger and with sofas! I do like the power points they've installed beside the dining tables.
Does anyone have any experience staying at the new airport hotels? I just might be interested if I don't get STPC. Not sure if the terminal will still be as 'quiet' once all EK flights depart from T3
