Huart, from Hull, said: "They were arrogant and just not helpful at all. Because of the ticket mix-up we missed a lot. We couldn't leave the village, it was like a prison.
"I was so upset I was crying, the kids were bored, I just wanted to come home."
Although Disney managed to sort out a room for the stay, they were not given a Genie card for access to the theme park.
To compensate for the error, they were given a fast-track pass so they could get on the rides quicker.
But when they tried to use it, staff told them the pass did not work and they were not allowed on the rides.
"They marched us to customer services and they even turned us away," said Huart.
"It was so embarrassing getting marched past all the other families, like we'd done something wrong."
All happy n ready to party x

Layton's birthday was the next day and his mother had organised for a meal and cake to mark the occasion at Buffalo restaurant.
But, again, because of the booking mix-up, they were told they could not have a table or cake.
She spent the rest of the day complaining to hotel management instead of enjoying what should have been a once-in-a-lifetime family holiday.
That evening, the family eventually got the correct tickets and re-arranged Layton's birthday party, giving the family a day and a half to explore the park, instead of the four they were promised.
"Layton also got to meet a few characters, just not as many as we'd like. Donald Duck tried to give him a kiss and ended up hitting him in the head and he screamed.
"Moana was really nice and gentle with him though.
"He still smiled all the way through but this is probably his only chance at a holiday. This was his last and only wish he will get and it was ruined."
A spokeswoman for Disneyland Paris said "We regret this particular wish did not meet the guest's expectations and we are now closely working with the family to resolve the situation."
A spokeswoman for Make-a-Wish Foundation said "When guest matters arise, we work with our friends at Disney to ensure the family is supported."
