I flew Allegiant Airlines last summer. Yes you have to pay for EVERYTHING, but if the price is right its worth it. For one parking was FREE!!! Yes FREE, It was great not having to get my car out of hock. Sanford Airport is small and easy to maneuver around. Its not overwhelming at all. If you have kids, bring snacks for them. I will suggest (if you can) bring snacks for yourself. The only thing that I didn't like about Allegiant is that in MidAmerica Airport (outside of St. Louis) they hand check EVERYTHING. Yes hand checking could be safer, but they made me dispose things that I have almost always taken with me. We had to dispose of Washing Liquid, Dish soap, my hair spray - Things I always took to Florida. On the bright side the airport was so small; I was parked right outside the door. This was 1 week before the liquid incident too. But I'd rather be safe than sorry, so thats really not a complaint!!!
