I can't speak for everyone, but if I'm a Florida resident without an AP I'd rather visit WDW between now and May versus the hot summer months. WDW is offering $225 for 3 days ($75 per day) or $240 for 4 days ($60 per day).
Universal's offer of $352 for 3 days at UOR ($118 per day, 1 park per day) is pricey for a consumer that is used to cheaper offers. (FYI - this is the cheapest ticket price, the summer averages around $454, or about $151 per day).
