We fall into your category of not always thrilled with everything DVC but still loving DVC and Disney as a whole.
Just like most things in life, there are ups and downs associated with Disney and DVC but on the whole it is by far the best vacation bargain we have found for the level of service and fun we experience while on vacation. Are there things we would like to see improved or changed, you bet. BUT we are still members and love going to Disney and enjoying our little piece of HOME every time we are at Disney.
The only other option we are considering is the possibility of buying a vacation home in the area. The downside is more upfront money, maintanence and effort on our part. DVC removes the headaches associated with owning a vacation home but it does come with the headaches of sharing your home and having your home managed by someone other than yourself.
Maybe if Disney maintenance continues to go downhill, dues keep going up and perks keep getting removed; we will drop out of DVC and get a house in the area. Right now we are still very happy and look forward to our many visits to the Disney and Orlando Area.
