Go, have a good time. I think the double stroller is a great idea. I love the fact that it carries most of the stuff for you. I have my 10 yo wishing for a stroller by the end of the night. I, by myself, will take my 5 youngest into the parks all the time. We will take the boat over to MK, but I usually drive us to the other parks (easier with the jogging stroller, cooler, fanny and backpacks). They are 3, 6, 8, 8, and 10. My 3 yo will not ride anything so I usually sit at the exit with her while the others ride. I trust my 10yo to tell me if the others were not following the rules in line (don't pull on ropes, no climbing and please don't suck the life out of people in line with you) and if they don't, they sit out the next ride with me. I am hoping the 3yo will ride this trip because it is a pain sitting all the time with her. However, my parents will be there with us on the next trip and they will babysit while I take the other 4. You will have a great time, have fun!!!!!!
