While I know there’s some risks with one-flight-per-day routes, SYR->MCO direct via JetBlue is our favourite way to go. Direct flight can’t be beat compared to doubling the worst parts of flying: takeoff, landing, taxiing, and boarding. Also I don’t know about MHT but the SYR flight leaves early morning, and the return from MCO leaves in the evening, so you’re really able to maximize your vacation!
