Luckily I did, which was a godsend.
Decided not to bother with a dayroom, as I landed at 5am and none of the hotels could offer a dayroom until 9am or later because they were full the night before. Didn't really fancy waiting around in lobbies for a few hours.
The OW lounge at TBIT was quiet enough (other than the loud lounge music), and having been up for the last 24 hours or so I had no problem catching up on some sleep in the lounge.
