Hi All....We are leaving for Universal tomorrow and it has been crazy; so plz bare with me. I just have some questions. First, can we use our room key to charge at the City Walk dining establishments and shops? Also, what is the best way to stay hydrated in the parks. Are the water bottles super over priced? We will be staying at Royal Pacific for 3 nights. Any advice on the best way to get over to the parks in the morning for early entry? It will just be my and my husband and our 15 year old son. We had him a little later in life than usual; so we want to do our best to keep up! Any advice anyone has on navigating the parks to good food and drink etc. is greatly appreciated.
