Thanks,
@Daver6 - If I'd need to hop in an Uber from the Novotel, then I'd rather just stay in town at a nicer property, I reckon

My flight out of BNE is around midday, so I've got ample time to get back there in the morning; but as I'm not doing anything the morning of, I figured waking up where I needed to be might be handy.
I'll keep looking at Pullman BNE and see if availability shows up. That's more the root of my query, I guess; i.e. does StayNight availability at a given property fluctuate over time, like it might for a reward seat on an airline, or is it more fixed than this?
Cheers,
Matt.
