Not yet. I had asked about this as well when I booked the land/sea. I eventually booked the land portion separate from the cruise portion for more flexibility.
For us, no, it did not come out to be the same price: the Land/Sea Package was more expensive than booking each portion individually. For others, it was cheaper.
We usually arrange our own transportation as well. We don't like going from resort to resort and picking up other passengers, so we book a towncar. Many of the towncar companies offer MCO-Disney-Port-MCO packages that aren't unreasonable.
