4 years visiting this beautiful place and just today I get a bad experience in the place where they sell fast food, I approached to ask them to sell me 4 disposable cups and they said they are free, I tell you in a good way that thanks but I need 4 q if it is to pay he paid and the person who attended me opened the bag in a bad way and practically threw me the glass that went to the floor.
I do not understand how such a nice place they have that kind of people
