I have done a lot of research, but sometimes hearing people's real life opinions is worth more than the research. I talked at length with one DVC owner while at Aulani and the conversation was quite helpful.
We are a family of four and our children just turned 8 and 10. Currently we do
Disney vacations every year--Disneyland, a
DCL cruise (I know it is bad to use your points on a cruise), or (this year) Aulani. We love Disney and I am the biggest Disney lover in the family. It isn't something we do "just for the children" or anything like that.
We plan to use these points at Aulani and at Disneyland. I've never been to Florida/Disney World and although we may go at some point in the future, it definitely wouldn't happen very often. We live in the greater Seattle area so traveling to Hawaii and California is much more affordable and interesting to us.
We fell in love with Aulani last week and envision ourselves returning there many times in the future.
I have looked into resale and am intrigued by it, but my husband would prefer to buy direct from Disney. He isn't very good at verbalizing why, but I know he likes the perks they are offering right now--which, to me, would be off-set by the amount of money we would save buying resale.
edited to add: My daughter enters middle school in September (yikes!) and our abilities to travel at off-peak times of the year will be eliminated. Prior Disneyland trips have been in February and September--that won't be happening any more due to her school commitments.
