You might be surprised at how good you feel and how easily you will be able to resume normal activities even the day after cataract surgery. However, you should observe a few precautions during the first week or so, to make sure you avoid developing an infection or sustaining an injury to your eye while it heals.
When you join in the pre-queue but are still 91000th in line for Harry potter and the cursed child tickets. â Gemma H (@The_Gemoirs) August 4, 2016. Number 97815 in the queue for Harry Potter and the Cursed Child tickets.
So if the lines are already too long once you get there, you can speculate on a shorter queue around 4:00 - 4:30 pm and visit the park first where you can easily spend a few hours. If you insist on visiting the palace first, the queue to get to the security checkpoint around noon can take 45-60 minutes.
