Hotel & Boss advice needed?

[Jessi]

I work for a small local owned hotel. My bosses who are the owners are 73 & 75. He was a politician for numerous years so, and he is a hypochondriac and doesn't like change. Neither are business people.
So this is a hotel. I have lots & lots of ideas that can help increase revenue & occupancy. However, My boss thinks everyone is out to get him when there is a bad trip advisor review (screaming, yelling @ employees - calling the trip advisor reviewer a liar...) So with my many idea even some that will cost absolutely nothing and some that are cheap ways that would indeed increase revenue & occupancy even if by just 1% he won't do it, and wants to keep everything exactly the same as it has been for 26 years.

How do you get someone like this to let you do their idea? & yes I've been here 3 years & been looking for a new job since day 1 being I didn't go to college for this. Any ideas on online based FREE advertising? I already do all the social media sites, web page, mobile web page, military based social media ad sites.) I'm tired of hearing him say how they are max on their budget but won't change anything that will increase revenue & occupancy. If Occupancy & revenue increase then it will not only help them pay bills, but give employees hours.

Some things yes I can sneak by and not tell them about if it is online involved. But even something as simple as having a snack vending machine where the initial purchase cost would be able to make it up within 18months or less he refuses to do.
I'm limited and I'm tired of it. If I could get them out of here and be able to have 2 weeks to do changes- I would be able to increase things. but they won't leave as the second he runs back into the office and sees one thing out of place (even one brochure tilted) he flips out.

HELP. Any Advice?
