I saw that post. Here's what I think- I'm on 24x7 as it is. Giving guests the ability to text me from their room, in their jammies (or less) that they need a towel is too much. Actually having to get up, come downstairs, ring the bell makes the guest think 'do I really need that right now?' Having a 'butler' they can simply text a msg to at any hour? No thanks.
PLUS, the whole idea states kind of plainly that I need to have the cellphone IN the bed with me just in case. When I shut down the computer at 9 PM, I am 'off duty' unless it is an emergency.
If you really need something, come downstairs, ring the bell and let me know. Don't even call the inn phone because I don't answer it after 9 PM.
A lot of ideas work if you are not already stretched to the absolute max. I actually NEED the downtime from 9 PM to 7 AM..
