Dear Customer.
Hello, this is Sue from VIP Travel. Thanks for your time to leave us a review. We will try to improve the things which you were not satisfied with.
The tour schedule can be changed depends on the situation (military issue or weather problem).
But this kind of situation doesn't happen often (only around 3~5 times a year).
Once again, appreciate a lot for your review and look forward to provide better service on your next trip.
