I'm going to be making a trip down the west coast of FL (IFR). I was planning CTY-V35-RSW. But I suspect that I won't get routed over the TPA class B airspace. While it's no big deal to get routed towards Lakeland, I would like the more scenic route along the coast. So is it possible to make a phone call and talk to someone about the possibility of the more scenic routing down the coast instead of the more inland routing? Like if you're at x,xxx altitude it's no problem or if you file this specific route, you'll probably get it. And if so, do you call TPA approach? MIA Center?
