Notes on my review; my wife and I went as a couple to HK (didn't bring the kids along) and were on a tight budget. We haven't been to any other Disneyland theme parks. But we definitely made this as a  cannot miss  itinerary during our first visit to HK. 1). Be prepared for a lot of walking   It is a large theme park, so make sure you wear comfortable shoes (or slippers sandals), bring sufficient drinking water (depending on how much hydration you need), and wear comfortable clothing (depending on weather forecast or season). Moving from one theme area to another involves quite a lot of walking if you sum it all up. I had my pedometer on and clocked over 13k steps for the whole day we spent there. 2). Buy your ticket online   Decided to buy our tickets online to save a bit and avoid the queue at the ticket booths there. So when we got to Disneyland we were able to skip the line for tickets and went straight to the entrance. (We went on a weekday so I noticed the line wasn't so bad. But it does add to the time you waste waiting in line) 3). Allocate a whole day for this visit   With the size of the park, plus the different attractions, rides or activities. You definitely will need to plan this as a whole day visit. We were there from 11am to 8pm (to watch the fireworks) and we were just a couple visiting. If your bringing children along, being earlier (be there by 10am) will definitely give you a more relaxed pace to go around and enjoy a lot of the attractions. 4). Weekend or Weekday?   Important note, we went on a weekday so I don't have first hand experience on weekend volume of people (its just a hunch). If milling around in a park with a LOT of people trying to get in line to the different attractions is NOT your thing then I suggest going on a weekday. Fewer people   shorter lines   more attractions to visit or ride. Granted there are some attractions that might be closed, but its just a handful so it was not a big deal for me. Longest wait time we had for an attraction was at the carousel and it took us approx 10mins to get seated. I can just imagine the weekday crowd pushing the wait time to at least twice that duration (just a hunch). 5). Bring your own water and food   being on a budget, we brought our own food and water. At first I was thinking these might not be allowed but we got them through and saved some money. For portability we brought a few sandwiches and 3L of water (for the both of us). 6) Notes on gadgets   make sure your phones cameras are fully charged and bring extra powerbanks and maybe memory (if you tend to take a ton of pictures and videos) if your phone camera has limited capacity. Having pictures and videos of your visit is a mortal sin (okay, not a sin but helps build nice memories) when visiting Disneyland. There are also certain areas with free wifi in the park so that helps you in updating your twitter, instragram or facebook accounts as you are experiencing the wonder of Disneyland. 7). Check the schedule of activities on their website or app   To make sure you don't miss on any major shows   activities. Make sure to check their website or app for whatever is happening on the day you plan to visit. This will help you decide what to watch or visit as some shows or activities overlap one another. 8). Check the HK forum for advice, suggestions and tips on Disneyland   I'm an organized   planning person, so doing research on where I'm visiting is a must. Check the HK forums here at Tripadvisor and you'll get tons of advice or answer to questions.
