$1500 saved is impressive! Did you join the $9 fare club? Best reason to join is for the discount on checked and carry-on bags. What airport are you flying from?
I have flown Spirit many times from Atlantic City, NJ to Orlando. I would prefer Jet Blue or Southwest, but many times, Spirit's prices can't be beat. Spirit has a lot of extra fees which you need to be aware of. You are allowed a small personal item to fit under the seat in front of you. Carryon in the overhead bid you pay a fee (a LOT if not paid in advance). Checked bags are limited to 40 pounds (all other airlines are 50#) and 62 linear inches. Seat assignments cost 10-40$ per seat per person, otherwise computer will assign you a seat at check-in. Seriously consider seat assignments if traveling with children. Pay for your luggage ahead of time BEFORE the 24 check in for best luggage fees. If you wait until you do checkin at the 24 hour mark, you will pay more. Wait to pay at the airport and the fees are OUTRAGEOUS! Check in and print boarding pass at home to avoid extra fees. Weigh your suitcase and keep to less than 40 pounds. Bring your own food for the plane, and purchase a beverage after you get thru security check before boarding the plane. Seats are pretty small and tight. It is tolerable for a short flight. Spirit has curbside check-in at MCO. My luggage has always arrived undamaged and with my flight. Spirit does not participate with RAC, but if staying at Disney resort you can use Magic Express. Mickey will take your bags to your resort, but you will need to put them on the Magic Express back to the airport.
I have only ever had one flight delay on Spirit (leaving MCO). ACY is a very small user friendly airport. Parking inexpensive and very close to terminal (across the street), very minimal security lines, and no long waits lined up on the tarmac. Very easy to travel with small children. Strollers and car seats are either gate checked or baggage checked free of charge.
FYI - Customer service is NOT located in the USA. I have only needed to contact CS once and it was tolerable and my problem was resolved.
Every time I fly Spirit I pray all goes smoothly, as Spirit is best known for their cheap fares, not their customer service. I have always flown in good weather months and paid for
trip insurance. I would perhaps consider flying another airline if I was flying during higher risk weather months where flights would be in jeopardy of cancellation.
Just my 2 cents. Hope it helps. Enjoy your trip!
