I think we enjoy Universal on a completely different level then the other folks.I completely agree, we have the gift of time and length of stays where we can meander every day and venture off the beaten path and have the time to appreciate all the small details that many miss. Those are the folks that usually complain they didn`t like the parks.
I never found the hallways too long at RP, although to be fair we`re usually near the beginning.
Yes, you did show us those hallways in WL....they are far spookier than anywhere else I`ve seen, glad to hear they`ve brightened them up since then. Such a gorgeous place though, I said at the time, if ever we were tempted to stay at Disney (doubt it) we`d definitely choose WL as it was just stunning. We left you that night wishing we were staying overnight.
We are there for the hole experience. Better weather than where we are from, relaxation, food, smell the roses, enjoy some rides, and enjoy time away from the hustle of life.
For most they want to power through as many rides as possible in 2 days and don't care about anything else. They would never notice some of the details you point out.
Also I think it's uncommon in the US for most people to be able to more than a few days at a time for vacation. For me it's a condition of accepting a job offer that they understand I WILL be taking a full 2 weeks to go to Orlando every December. We love it like you do and are never bored.
