Fair play to the OP for realising her naivete. It's a mistake a lot of people fall into, assuming that the cause of homelessness is simply the lack of a roof over your head. Those of us who have worked in housing, substance misuse, prisons, social care and the like, know very different.
That's not to say that homeless people are the shit under everyone's shoes and undeserving of any help.
In areas of high homelessness levels, there are specialist doctors surgeries in place for rough sleepers/vulnerably housed who are not necessarily able to keep to an appointment system.
Hostels have trained and experienced support workers teaching the basics in life skills and how to manage a tenancy, because throwing an entrenched homeless individual into a rental without teaching these would result in chaos and eviction. These hostels are accessed through local councils and are available to apply to live in all year round .
Local council-run rough sleeper teams who engage with those who refuse help offered, making sure they are at least as safe as they can be. Most RS teams have a dedicated mental health worker who specialises in homeless mental health.
Drug and alcohol agencies will engage with anyone who does so with them, and will find people dry accomodation to try and break the cycle of their addiction.
All of this is dependant on the individual choosing to engage with the support on offer. Many choose not to. That is their choice and should be respected.
If there were individuals wishing to use these hotel rooms, then they will have already chosen to refuse the emergency severe weather protocol . Ask yourselves why that could have been. And then ask yourselves, if your daughter was working the nightshift at this hotel, would you want her managing the chaotic behaviour, substances/alcohol, possible violence, of 19 rough sleepers so entrenched in that life that they've refused even the emergency cold weather accomodation.
As an aside.. to anyone who volunteers 'at christmas'? in my shelter we had such a huge amount of people requesting to do this, we had to turn many away. They were most put out. We did remind them that the shelter is open 24 hours a day, the other 364 days of the yer, if they wanted to pop along another time.. guess what, they didn't!
