Again, this is not at the north end but my recomendation is for the Parc Corniche
http://www.parccorniche.com/.
Before I joined DVC (Plug, plug

) I stayed there exclusively. In fact, if I run out of points during the year , I still go back now and then. They're a stone's throw away from Seaworld, good sized suites (all the rooms have their own kitchenette) definately worth the money.
