Unofficial Guide Fan, Big-Time
Thought you might want to hear from a tried & true UG user. First used the unofficial guide back when it was a thin thing, circa 1989 or so. And loved it! It was a prize trip my 10 yr. old won, only had "4 days/3 nights" so we planned to go to MKthe day we arrived. Checked into hotel at 3 P.M. and rain was just pouring a deluge...I looked at son & said "UG says the harder it's raining, the better it will be." He voted to go to park--we went and just like the book said, cars were 4 across, bumper-to-bumper leaving the park. We got in, got close parking, and rode ride after ride with no waits--usually exiting and walking right back on for another go. Have since used updated versions for every trip-4 times, for visits with everything from preschoolers to elder-teens. Works wonderfully--especially for planning with teens & little ones (if you're willing to let the teens stay in the parks when you leave for mid-day break.) Managed to hit all the little one's choices (like Dumbo) before major crowds, and all the big kids stuff (like Space Mountain), ditto. We'd go back in the late afternoons/evenings for leisurely strolls, shows & sightseeing, catching rides where there were no lines.
We never had any problems following the plans--their advice to send the fast & trustworthy to sprint ahead for the fastpasses is soooo good...it worked for us every time. Agree with poster about using the early magic hours...the books used to make it clear that the advice not to go on those days was for people who did not have the early entry perk (non-WDW hotels) -- because by the time the general public was admitted at regular park opening time the parks would be packed with WDW hotel patrons. Somewhere along the line, they changed the advice to apply to everyone, and I don't know why. We've always gone at the earliest time for the early park opening & have always had a great time...many times leaving the park just 2-2 1/2 hours after getting there, having ridden all the major rides at least once if not twice & seen the major attractions. Then spent 4-5 hours swimming, eating, etc back at our hotels. We did this as recently as 5/2007. (we've gone the week before Memorial weekend every time.) Hope this helps.
