Hello,

You have some good ideas there. Even though I am not a marketing executive of a hotel, I believe I can add to your list... because I've dealt a lot with marketing executives at our local hotel and I attended every marketing / strategy meeting.

1. Establish a partnership with local tourist clubs or buy an advertisment in their local semi-annual publications.
2. You can advertise in your local airport or airlines where they have a promotinal brochures, catalogs on every flight / plane and some people would need a hotel room to crash at.
3. Investigate and then join local Chamber of Commerce. Chamber of commerce has many events and they have a network of businesses / executives who often need to use a hotel conference room. Or better yet, invite your local Chamber of Commerce to host their monthly meeting at your hotel. Our chamber of commerce has a Power Networking meetings (every month), and every month it's in a different business and in differnet location. Many companies welcome Chamber of Commerce to host their meeting in their facility because it gives them good publicity and advertisment and exposure! Recently they've held their meetings in large hotels such as Hilton, Radisson and others. In our town (Indianapolis) usually around 750 business people attend power networking meetings held by Chamber of Commerce. So it's another way for you to get exposure.
4. If you have any hospitals, businesses near by, approach them and set up a refferal program or work with them some sort of deal that they'd send their visiting business people to your hotel. Here in Indy, the hotel with whom I'd worked is located near by a hospital. Many people come to this hospital from other states and relatives of those patience need a room. So the hospital was sending patients directly to that hotel.
5. Attend any local networking meetings.
6. Establish a partnership with local small travel agencies.

That's all I can think of right now. If I'll get any more ideas, I'll post them.
Good luck advertising!
