Has anyone flown with Allegiant before?

We're going to be driving along the Blue Ridge Parkway after our Disney stay in October.

After some research our options have been to either fly from MCO to Atlanta or Charlotte. Charlotte seems to be too expensive compared to Atlanta, but some of the timings for Atlanta aren't great with certain airlines (and we want to maximise our time on our last Disney day!). It would then be somewhere between 2.5 and 3.5 hours from the airport to our first night somewhere around Maggie Valley/Cherokee

I've now discovered I may be able to fly into Asheville (where we were going to be going anyway!) which would save us a lot of travel time on our arrival day, and the flight departure time would also work for us. I've never really heard of this airline before though... has anyone got any feedback?
