Yes it is. you get Express access for your entire trip including the day you check in (even if your room is not ready) and the entire day you check out.
Thanks! I thought last year that I saw on their website that you could buy an add-on to your ticket that would give you front of the line access if not staying at the resorts. Is that an option?
Yes. That is still an option. It is called Express Plus and the cost varies based upon the season. You need to buy Express Plus for each park. It entitles you to express access to most of the rides one time. The on-site hotel privilege still allows unlimited access for most rides most of the time.
