As per passport (IMO this is the hotel's photocopy - shows the two room numbers):
Interesting to note that it appears the hotel cancelled out the room she was staying in with her mother and changed it to the room that TS was staying in? So neither of them had any business being in Sheila's room if HM had officially changed rooms at the reception desk? Maybe SWM didn't secure that room for TS, maybe he did have a credit card of his own to hold the room but no credit left on it to pay for the room?
