Yes you have to call - but it's worth the phone call - Call toll free (877) 939-3732 - they can set you up with a 9 or 10 day pass (tip: if going back soon buy the 10 day as it's all of about $15 more) I think the reason you have to call at all is b/c they did all the online stuff first and then had so many requests for the longer passes they added them as an after thought... But with the toll free # it's not a big deal...
