We did the same trip...7am from Boardwalk and went to World Showcase Lagoon, but in Nov. Due to the weather though, it was unseasonably cold, we didn't catch any fish, and the guide only caught 1. He charged us half price because of this, but even if it had been full price it was worth it. Very relaxing and enjoyable, and being able to go to WS Lagoon was great. We'd definitely do it again.
