These comms are between RO near apartment and MO near main reception, see RO rog, the subject, at least of the first 6 comms, is: when will police get to apartment. The GNR arrival at apartment is IMO after the 2nd voice call. So the GNR arrive at apartment shortly after 2306 IMO.
A later possibility is that GNR arrive at apartment at about 2325, if so then the 2324 txt in this list, and the brief voice calls at 2314 and 2317 between two other mobiles, would also need to be taken into account.
Based on this, I would place the GNR at OC reception no later than 22.58.
I R old, but I can still walk from Vale Verde restaurant (22.52 second call) and make it to OC reception before 22.58. It is simply not that far.
Let's see. Phone call around the 'hurry up' second message to GNR around 22.52. Presumably something short to Rachael, like 'we're calling again'.
Then a flurry of text messages around 22.58. Like 'there here'. Like Sylvia B is talking to them. Like Gerry is talking to them. Like we're coming to 5A now.
Definitely not the later time unless after the hurry up message the GNR stopped for a meal at Vale Verde restaurant.
