logic

Visa debit and credit are not the same thing by any regards, so no. Perhaps they'd be willing to take your money as a deposit though, but then you run the risk of a very complicated refunds process that could take several weeks.

Finally I can use my hotel experience to use!

Unless you have an American Debit you cant pre-authorize on Canadian debit cards as far as I'm aware. However I'd say a majority of hotels take debit deposits (usually $150-$200) plus room plus tax. They usually make you a "cash-only" guest which means taking away your phone/PPV/mini-bar services and room charges at restaurants or other facilities within the hotels services are disabled as well.

By standard at check-out an employee has to go check your room prior to check-out to ensure no damage has occurred and any appliances have been stolen before they can give you back a deposit. 

Its definitely more effort than its worth, everyone in the hotel industry prefers credit as its much easier to check-in and check-out guests. **Side tip, never use pre-paid credit cards, they will not work and you will have a hard time getting your money back because a deposit on one of those credit cards creates a black hole for the funds...Hope this helps, lemme know if you have any other hotel q's!

Yes they would! Me and my gf had the same valentines idea as you
