Sandy,
Sounds like my family too!!! Everyone who has read my posts know that I am so excited to take my mom, sis and BIl to a 2 Bedroom at OKW. Well, at first we just invited my sis and her DH because the people we were originally going with backed out. We didn't invite my sis because she is family, we invited her because we truly like hanging out with her and DH. The next thing I know, she invites my mom. No problem, I've always wanted to take my mom!! Again, although this may "appear" to be a family reunion of sorts,
It' isn't!
Well, last week I get this call from Dsis who says other (Not so Darling) Sis wants to go also, and DH and I can have our points back and get a smaller room, and she'll room with other sis because she doesn't want to ruin our vacation,
SHE doesn't feel she can very well tell my other sister she can't go and
blah, blah, blah, blah, blah!!!!!
HELLO? 
Ruin our vacation? I think ya just did. I then went on to explain that we had to rent points so that we can all go and even though other NSDsis thinks that this is a family reunion, it IS NOT and that this is our vacation and we asked you because we wanted you to go and don't do this to us!!
See, NSDsis and I do not get along. I don't know why? I've tried and tried with her! She is rude and condesending(sp?).

And, we argue
all the time!! And while I may be able to get through a day with her and bite my tounge,
I refuse to have to on my vacation! I don't care if there is 48 square miles and someone can walk away (which is what Dsis tried suggesting) I'm not walking anywhere.
NSDsis, when I did talk to her, goes on to say that I did this on purpose. I planned this family reunion to leave her out because I knew that she's a teacher

and wouldn't be able to go the first week of Dec. and that
she's not the one to start the arguments, I am

and blah, blah, blah, blah, blah. And, did I say blah? I then replied, "See, we're arguing right now. What makes you think we could get through 6 days of not arguing?" I don't really care who starts the arguments, I admit, sometimes it is me but hello, is this not my vacation? And why, NSDsis, would you want to go when you don't even like Disney and we argue all the time especially if I'm the one who always starts the arguments? She replied because she didn't want to be left out. Now I know many of you are feeling bad for NSDsis by now but really, she told me that she never starts the problems, and that she does not see what part she plays in the bad situation. Well, in my defense, I can only do so much to try and make things better but it's not fair to put all the blame on me. I'll take half, heck, to make you happy I'll take 3 quarters but I won't take all the blame!
I then find out, that DSis (who I'm starting to think is Not So Darling) told NSDsis to go ahead and come along, buy your plane tickets! Well, when I find this out, I take a VERY DEEP breath

and say to NSDsis, come on, we'll make it work somehow. To which NSDsis storms, "NO! I'm not going! Just go and have a good time! Don't worry about me!" OK, suit yourself.
Of course, mom doesn't like to see her children fighting and probably feels I was too harsh on NSDsis and DSis is feeling bad because she thought it would be alright for her to go and even told her to buy her tickets and I'm feeling bad because everyone else thinks . . . I don't know what everyone else thinks. But to make this terribly long story short, what was supposed to be a great trip is making me feel quite ill!!
My DH says we will never try to do this again!! Of course, DH thinks we're all crazy

Thanks for listening.
