I've been to Disneyland in Anaheim, California and Disney World in Orlando, Florida in the United States, and this is definitely the most compact Disney park I've been to. But there is an advantage to its small size: You walk less. This is especially advantageous if you have very young children. In Disneyland or Disney World, you must do so much walking that even the adults poop out after half a day. The HK Disney Park is so compact and if you go on a weekday, you could finish visiting the Park in half a day! I was there today, arriving by MTR in the morning at about 10:45 (It opened at 10:30). There were no long lines awaiting to go in. I went straight to the entrance turnstile and show the attendant my ticket code (I ordered the ticket online early in the morning), and he processed my ticket immediately. I walked down Main Street (by passing all the photo opportunities with Disney characters) and went straight to Tomorrowland. There I immediately went to the Iron Man ride which I expected to be the most crowded since it's Disney's newest ride. I was surprised that I was in my seat within 10 minutes. I followed it with Hyperspace Mountain, Starwars Command Post, Buzz Lightyear Astro Blaster and Orbitron (since all were in Tomorrowland), and all waited no more than 10 minutes. I then went to the next theme section, Fantasyland, and tried their most popular ride, Winnie the Pooh, and once again the wait was no more than 10 minutes. I followed that ride with one of Disneyland's best known, It's A Small World, was able to walk right in. Then went to see the shows Mickey and the Wondrous Book and Mickey's PhilharMagic, and once again walked right in without waiting. I wanted to watch Festival of the Lion King in Adventureland but it was closed until April. So I went to Grizzley Gulch but decided I did not care to ride the Mine Cars Rollercoaster so I proceeded to the Mystic Manor which is similar to the old Haunted Mansion and once again was in within 10 minutes. I entered the park at 10:45 a.m. was actually ready to leave at 3:00 p.m. If it were not for the afternoon parade which started at 3:45 p.m. I would have departed at 3:00 p.m. I did not have to use the Fast Pass feature of my ticket at all and was able to repeat a couple of rides with very little waiting. So from this, I conclude that you can do this park in one day if you go on a weekday and arrive by opening time. But like all Disneylands, I recommend you have a plan of routing before going to save yourself time and unnecessary steps. Here are some of my suggestions after being there today: 1. Order your tickets online to save waiting in line to purchase tickets. 2. Bring water and small snacks (cookies, chocolate bars, trail mix packs) but leave your lunch size sandwiches behind as park security will not allow bringing food items into the park.3. The MTR ride from the Hong Kong Station to the Disney Station takes at least half and hour, so allow yourself adequate time for transportation in order to get there by opening time.4. Once you enter the park, by pass photos with all the Disney characters on Main Street and go to the Information Board to the right of the Circle before reaching the Castle and check ride closures and show parade times. 5. Then head straight for the first ride on your planned route. Most people in Hong Kong don't seem to be early birds so you should not have to wait long for these first few rides.6. Be sure to work in the shows into your schedule: Mickey & the Wondrous Book, Mickey's PhilharMagic and Festival of the Lion King. 7. Lastly, also work in the afternoon and the evening parade (if you're staying til closing) as well as the fireworks show to complete your Hong Kong Disney adventure.
