There is way more stroller parking than
ECV parking. We rarely saw a large ECV only parking area. Most of the time we parked it with the strollers or somewhere else up against a dead end out of the way. Be prepared though for CM to move your ECV even though they aren't supposed to! Even when you take the key they have a way of moving it. Many times we got off an attraction with a little bit of worry because the ECV wasn't where we left it. We tied a little ribbon around the basket and it helped us spot ours amongst the others. Good luck!
