Personally, I would go with Boardwalk as my 1st choice and the YC as my 2nd. I like the theme of these two resorts and I'd prefer to be closer to clubs, dining and shopping offered at the Boardwalk. Just my guess, but I would think that the Stormalong Bay pool at the BC/YC draws alot of kids.
When I travel with my family, I look at villas and rooms where we can spread out alittle bit more. When travelling with just DH and myself, a hotel room is fine. That's just us though.
