Is it standard practice for hotels, in this case Hilton, to charge hotel guests for visitors?
Asking because I had an incident at the Doubletree In San José, Costa Rica where the front desk clerk told me I was not allowed a visitor without paying $60. This after I had had visitors a few times before that with no mention of a fee, and an email I received later from the front desk manager seemed to infer that it is a company wide policy to charge $60 for visitors. When I pushed Hilton Guest Assistance for clarification on this, they went silent.
Additional info: This was the 14th night within a month that I had stayed here as a Diamond. The visitor was a Costa Rican woman, actually my best friend. It was 11am, and I was checking out at 1pm. We do remote construction design, and she was coming to work with me. And lastly, she had been there as a registered visitor 3 other times during those 14 days I had been there, but the obvious difference with those visits was that she was either with her boyfriend, or another friend of ours, also a male, that we work with. This time she arrived alone.
My feeling is that this guy presumed she was a prostitute, because why else would a Costa Rican woman being visiting a gringo at a hotel?
Am I crazy? I’d like to hear other opinions on this.
