Speaking before the security changes were announced, she told the BBC: “I think it doesn’t overly matter what someone knows about someone else, like personal details.
“It wouldn’t be OK for you to issue a key to my room without my consent.
“If hotels aren’t doing that, they need to contact the person before they give a key away.”
The woman said her room did not have a chain across the door.
“Maybe that should be mandatory in all hotels, so that you remove a little bit more of the risk,” she said.
“One of my biggest concerns, and from looking at everything online, is how many people do get access to people’s rooms.”
Labour MPs Matt Bishop and Jen Craft are due to meet with Boydell later to discuss security at the hotel chain.
Commenting on the upcoming meeting, the woman said it was good the issue was being highlighted, adding: “There needs to be better procedures for the issuing of keys, for giving out anything to do with rooms, really.
“It’s frustrating that it takes something like this to then push those kind of things forward but I’m glad that they’re actually looking at it.”
The company, based in Thame in Oxfordshire, said Boydell had also requested a meeting with the safeguarding minister.
