And SFB is much smaller and quicker/easier to fly in/out of.... since MCO is so much larger, and takes ~15 min more (at least) to get to/from your gate. That said, SFB is about 30 minutes more driving time to WDW or Universal.

The primary difference between Orlando International Airport (MCO) and Orlando Sanford International Airport (SFB) is their scale and proximity to the main tourist hubs. MCO is the massive, world-class hub located just 15–20 minutes from Walt Disney World and Universal Orlando; it handles almost all major domestic and international carriers. SFB, on the other hand, is a much smaller, quieter airport located about 45–60 minutes north of the theme parks in Sanford, Florida. SFB is primarily used by ultra-low-cost carriers like Allegiant Air and some international charter flights from the UK. While SFB often offers shorter security lines and faster baggage claim, the cost of transportation (Uber/Lyft) to the theme park area is significantly higher than from MCO, which can sometimes negate the savings of a cheaper flight.
