Yup, the net is lowered each evening once Marvel Island is clear of all guests.
All items (even if they are in pieces) are taken directly up to lost and found. Loose change is taken to McElligott's (sp?) Pool in Seuss Landing so it can be donated to the United Way of Central Florida.
Only thing to note is that, when the wind starts to pick up - the net starts to move quite a bit, creating a "wave-like" effect. This makes almost everything in the net be thrown off behind Cotton Candy into the lagoon, making it self-cleaning. All items in the lagoon area under Hulk are retrieved about once every week or two by tech services, depending on their inspection schedules, and given to operations to deliver to Lost & Found.
