My phone call was never returned after trying to speak to a supervisor about switching my reservation day due to a medical emergency. Now my vacation is over and I am out $300 because I was not contacted back after being promised on a recorded line that a supervisor would call me back before the end of the day to make these changes and plans. User's recommendation: Do NOT buy tickets ahead of time because if your child get sick you’re out hundreds of dollars and they will keep you on hold for days on purpose.
