I use a debit card for almost ALL of my hotel nights. I have NEVER had a hold put onto my account for 14 days. Never. It can be as long as three days, which, in my mind is understandable, given that it may take them a couple of days to reconcile any outstanding items that may have been charged to your room in that time. Of course, I do speak of three BUSINESS days - but, honestly, it has never once affected my own account.

If you really do have that little leeway on your debit card (and, understand, I am not making a judgement - just an observation), you really should use a credit card or pay a cash deposit, which you can recalim at checkout.
