Although I've never been to BC, we just returned from HGVC International Drive and absolutely loved it - would go there again in a heartbeat. I posted a review on TUG.
Even though we didn't have any kids with us, we did notice MANY activities going on and all the kids really seemed to be having a great time. One day the resort rented a huge blow-up water slide for the kids. They also have dive-in movies on a big blow-up screen 2x per week. Kids can swim and watch, parents can lounge on lounge chairs and/or spend time in the hot tub nearby. (They showed the Spiderwyck Chronicles the one night we went down.) There is also a lounge with 2 pool tables (free).
We spent one whole day by the pool, there is a deli right there, a full-serve bar, and a restaurant that serves such dishes as chicken strips to fettuccine alfredo. The best thing is you don't even have to get up - just flag a waiter/waitress and everything is taken care of.
As for the newness, we stayed in the newest building (#7, which I requested), and it had QUITE a WOW factor. I'm sure your wife would be impressed.
The location was great, too. We went to Hollywood Studios one day, Downtown Disney, and Universal 3 days. Nothing took more than 15 min. to get to.
If you would like any more info, feel free to PM me - I took tons of pictures of the main pool area and the unit.
(Just for comparison sake, we usually stay at Marriotts, don't often go out of their system. HGVC service - the little things- was better than any Marriott I've yet been to, and I've been to many. Also, the units and facilities is right up there with the best of the Marriotts that I have stayed at.)
