I'm contemplating skipping RoTR for our January trip and just riding it in April during my solo trip. We have a FP for Slinky Dog at 3pm and dinner at California Grill at 6pm. Our original plan was to get to the park around 11am, ride Smuggler's Run and the HS classics, and head out by 4pm to get washed up for dinner.
My fear is that we wake up at 5am, get to the park by 6:30 (7am opening the day) and end up with a boarding group that will force us to cancel our California Grill dinner. If this ride is totally worth skipping a signature dinner, please persuade me!
