Orlando isn't locked in to the 4/5 seed, they could get a 3/6 regional, a 2/7 regional, etc. The way the committee brackets the field is they start with the 1 seeds and put them as close to their campus as possible, then the 2 seeds, 3 seeds, and the 4 seeds get protected last. The better the seed we get, the more likely we will be drawn into having Orlando as our location.
That said, there aren't a ton of Southeast teams in contention for a top 4 seed that would have Orlando as their closest spot. Assuming we get a top 4 seed, the chances that we get drawn into Orlando are relatively high, regardless if we are a 3 or a 4.
