A warm welcome to you, Trang!
Thank you for coming by planDisney with your question! I grew up visiting the Disneyland Resort in the summer and there's nothing quite like spending an entire day in the Parks from morning to late evening, enjoying the warm, sunny Southern California days and comfortable nights. It brings back a tremendous sense of nostalgia for me.
The three day
Park Hopper is a great ticket choice because you'll have plenty of time to spend in both Parks. In response to your question, you may absolutely reserve non consecutive days. However, please note that, per the
Terms and Conditions, multi-day park tickets must be used within 13 days after first use, so factor that in if your visit is an extended stay.
Reservations are released 120 days in advance, so be sure to mark your calendar and secure your reservations when they open. As the date draws near, it might be more difficult to obtain reservations but you can keep checking the
availability calendar, as openings will periodically appear as folks change their plans.
July has historically been considered a peak month, so expect heavier crowd levels. I would highly recommend purchasing
Genie+ to take advantage of
Lightning Lane entrances and avoid the standby queues. If you are willing to split your party, also consider
Single Rider Lines, which can save you a lot of time as well. No events have yet been announced for July 4th, but last year there were many tasty
food offerings as well as special
performing bands! And what July 4th would be complete without
Fireworks at Disneyland Park?!
I hope that I was able to answer your question, Trang. Summer is my favorite season and the Disneyland Resort is my favorite place, so put them together and it just makes sense! I hope you have a fantastic time and please come see us again with any more inquiries!
Have a Magical Day!
