You might also want to consider what's actually open.
I believe the IC O2 and Park Lane are still both closed.
The Park Lane keep randomly changing or removing the projected date of their opening. The last date I saw was 1st Sept,
There is no date for the IC O2.

So they may take the booking, but in these times there is still a risk the hotel will be closed.
Based on my other bookings, the hotel will cancel the booking and email you the bad news. In one case this was 2 months outs, in another it was 10days before.
