I've been reading a lot of threads regarding sales & marketing but haven't seen much about the hospitality industry. Is anyone in this industry, and if so what aspect?

I am hoping someone can bring up some new marketing and sales ideas. Here's what I have tried so far to increase occupancy:

1. Used the franchise database to send targeted emails and postcards advertising our hotel.
2. Marketed towards local churches and schools.
3. Bartered our rooms for advertising at large local events.
4. Partnered with several internet sites to take reservations on our behalf.

Our hotel is priced below the other area hotels that offer more services and amenities, but we are priced slightly higher than the "bottom dollar" franchises....so adjusting the price is not going to be the answer.

I know we could stand to benefit from some additional "guerilla marketing" but it has been hard to find the time for that. Can anyone think of more ideas that can help me in marketing my hotel?
