Hello. My husband and I will be taking our two girls, ages 7 and 6, to Disney World for the first-time in the Spring of 2016. My husband's last trip was when he was only 3 and I've never been, so we are all basically first-timers. Our plan is to stay 6 nights, but only go to the parks 4 of those days. From my research, two of those days need to be MK and then we want to do Epcot. We don't want to pay the extra for the park-hopper. Question is where to go for the 4th day? Is DHS worth it?
