I went from an Odyssey to a full size suv and don't miss a thing about my van. Yes, the sliding doors were nice when they were little, but it doesn't sound like that is your situation. I don't feel like I lost anything storage-wise but I went to a Yukon XL so it's huge. With one kid, I would shop for something fun to drive since I think most suvs with a third row could work in your situation.
