I love the value resorts, so it would be no problem for me to go from the WL to a value resort. Just check with WDW to make sure you still get the
free dining.
August is hot, so the nice thing about the WL, in the heat, is that there are a lot of inside areas for the guests. With the value resort, you go from your room to the heat. In the WL, you stay indoors. The walk to the boat to the MK, however, is like being in a sauna.
Bus service seems to be better at the WL, than the value resorts.
WL is nicer, but how much time do we really spend at the resort? Mainly, for a good nights sleep.
To be honest, I think that kids like the value resorts more, because of the theming - it is just so childlike.
I just do not know what to tell you about the kids. WDW is for kids, and the kid in all of us, but first and foremost for kids. If she can afford it at a value resort, then I would change and go to a value resort.
In any event, I would sit down and have a good talk with her - tell her that you love her, but that she is irresponsible, and her irresponbility is seriously affecting her kids. The one thing that we take seriously is our WDW trips. We plan them for months, in fact, our upcoming December trip was scheduled last September. We save for many months. We have had to cancel some week end outings with the kids, because we were short on funds, but never our WDW trips.
Does your sister spend money foolishly? Does she live in the Mall, buying piles of clothes that she never wears? If so, then she really deserves to be reprimanded.
Would this be her kids' first trip to WDW? If so, then I would call Protective Services. Just kidding, but irresponsible adults rub me the wrong way.
Above everythng else, she is your sister, and something like a trip should never, never, never come between sisters. Make sure whatever you say to her is said with "love". The trip will be over, and yes WDW trips create lifelong memories, but she will always be your sister.
PS - Never again plan anythng with her, that involves over a couple hundred dollars.
