[Travel Guru]

On our trip in october, i was suckered into taking my Dh's cousin ( 39- kim) and her daughter( Rachel), who is turning 11 as we go. She is an angel, so much fun to be with, and polite, if shy! We are also planning on taking his other cousin,( 13-Nichole) :eek: who is the niece of Kim. Phew, I LOVE extended family! We are going in 6 weeks and 4 days. I have also been suckered into paying for the WHOLE thing, then they are paying me back for their share. It is gonna be on the Disney Rewards Card for points..... I am paying on Saturday!:crazy::shocked::eek: SOOOO, the 13 year old had been acting like a little witch, as they so often do. She is smart with every comment, wants to be the center of attention, is too :cool: to be with us, and never does what I ask when she stays over.... She has been on(Disney) probation all summer anyway for her attitude Then yesterday, the Kim tells us that Nichole didn't want to come see us because she had other things to do( a new kids Christian band) . She has also decided that if she has beand practice, etc, then she won't go. ... So, I put on the brakes and set down an ultimatum. I want to know by Sat if she is going, NO BACKING OUT!~ Her mother texted back and said "And what?" GACKKKKK! I am almost about to pull the plug on her anyway, $700 is too much to spend on her being a butt for 9 days! help meeeeeeeeee??????? ok, sorrry, what do you all think?
