Hi,
Should not be a problem at all. It's still off-season in March. My husband I are only a 5 hour drive from HH and frequent the resort in March and November. If you are staying there over the weekend you may want to consider member cash, the points are really high on the weekend. My husband and I just returned from HH and our two-bedroom unit was only 115.00 / night, and they had still had a few rooms left for member points 1 month out from our stay.
