Go. It's amazing. Fabulous. One the most magical places in the entire world. The budget minded can take the bus from Maun to Sepopa. There is now a river taxi that travels daily from Sepopa to Seronga and coordinates with the buses. If your timing is off stay at Swamp Stop overnight. In Seronga you can stay at the Polers Trust and enjoy the mekoro trips.
Much of the area is divided into large concessions run by various safari groups. Development is strictly regulated so that there is little development and lots of wildlife. It is expensive, but worth it to stay in some of these permanent tented campsites. The guides are knowledgeable, and the accommodations very comfortable. Wilderness Safaris runs many great camps. They are all inclusive: two wildlife rides a day, all meals, snacks and drinks are included in the price.
