Okay, thanks. I was trying to figure out where RD was, thinking it was a place rather than a thing. Time will depend on which theme park you're going to but...
It will take you around 15 to 20 minutes to get to the various parking lots from the HGVC I-Drive location, then parking time and transportation time to a park. Magic Kingdom takes the longest from parking to getting to the theme park, through the turnstile and to the rope because the parking lot isn't right in front of the park. I guess I'd generally suggest heading out 45 to 60 minutes before rope drop time.
Have fun!
