Here’s the real deal:
I have seen many people fishing with those cane poles, and I have NEVER seen anyone catch a fish. In the water, I have seen a few blue gill (about 3" long or so!!!), but have yet to see one of those whoppers actually hit a line.
If you want the real fishing experience (which will include some enormous large mouth bass!!!) you need to do a fishing excursion, which they offer at several places with large bodies of water. I would avoid the lake at Marketplace and instead opt to head out into Bay Lake (you can leave from WL or Contemporary) and really pull out some big ones.
You’ll get a B.A.S.S. guide who knows the waters and you will get some amazing photos. Ask them to take you back into the swampy areas behind Contemporary as well as along the islands in the middle of Bay Lake. This is totally worth the money if you really want to catch fish.
