I think that would be pretty unfair on the boys. Could you have
the party one day then do two separate sleepovers at other
times?
You could do one sleepover after the party and then one another
day but I think who ever does not have friends to stay will be
feeling down, flat and fedup if you do this.
How would you feel?
I think that it would be okay because the guys won't really
think that they would be invited to the sleepover part anyway.
