My husband and I are going to DLR the weekend of March 3rd for our 15th anniversay. I got a great deal at The Hilton by the convention center ($84 a night, government employee rate). I have never stayed over there. I have only stayed on-site or right across Harbor. What is the best way to get to the parks? Is it walkable? If so, is going past the PPH then through DTD the way to go? How is the ART? Does it take forever to get there? Thanks!!
