I've only stayed at the Fort in the cabins. We've been using our points for DVC stays/resorts the past 10 yrs! So this will be a switch, staying in an RV but we are really excited about it and also about bringing our golden retriever, Molly. We've done the family trips in summer the last few years. If you go early, ride and come back for a break and then go back to the parks at night, you will be fine. Follow the "go to the parks the next day that have the late night the night before" and you will see a noticeable difference in crowds. Have fun!
