Pros: Nothing! They made me very upset!

They said I needed a vista for the length of stay which I always get when I am in Manila for the past 8-10 years that I have been going without any prior warning before I confirmed this booking! I was charged $500.00 to change the departure date! Outrageous!

We attempt to get accurate prices, however, prices are not guaranteed.
