I've stayed at the B resort before and liked it well enough but didn't try out their shuttles to the parks. I've read that they pick up 1 hour before parks open in the am and 90 minutes after the parks close to bring back people to the hotel and that they run every 30 minutes but I didn't see if they share the shuttles with other hotels in the area and how long it takes once picked up to get to one of the parks.
