You also not have to forgetting that was missed in the posts so far, that you can´t decide which Park you would have Early Half Hour this decision is made for quite some time by DISNEY themselves they decide which Park has it not both anymore sadly means to check on park hours before doing the park reservations.
Mostly on Sun and Mon DCA it seems to having their early entry and TUE, THU and SAT for THE OG Park and WED and FR for DCA as well.
So checking it before your trip and before doing the park reservations would be not a bad idea since that rythm could vary who knows what they planning during a Year before it was easier for visitors on-site.
For this new way I planning to visit it first when early entry than hopping to the other park but yeah it depends on how much you are travel with you as Solo Traveller it is way easier to do and for me the park hopper is worthy even when I will not use it every Day.
Also for some
Genie+ makes sense for others they think it doesn´t depends when you be there and how much you care if it works or not it can help but it may could not I will take it but not sure how much of a help and ease it will be but I had it 2 yrs ago in WDW and okay not that easy but it depends on own point of view.
I would watch some useful vids on YT for that service to see how it works and you could check wait times on days you want to be there to see how it does and if it would be useful depends of group sizes as well since $30/day/Person isn´t cheap even for me as single Traveller it is not really easy and cheap.
So good luck and don´t forget checking out the park hours to be prepared but with park hopper you can make it easier I wouldn´t consider DCA as half Park but okay some did and since Disney paused Entertainment kinda yeah if those extra shows wouldn´t perform it is getting less excited but okay.
But I would consider doing a fully Park Day in the Original Park itself since it has the most Rides Shows and Entertainment FANTASMIC is back (without a Dragon at the moment sadly) and also they having some SW Galaxy´s Edge Fireworks after night kinda Show in Batuu Area and they having a Nighttime Show at Main Street U.S.A.
And at Halloween Time a overlay of HM from Aug 23rd with Virtual Queue means getting online on your phone and get a boarding group for that. And their is a unique Main Street U.S.A. Tour seeing Walts Apartment at Firehouse for around $169,- expensive but something special.
Also good Food and Snacks in the Park Golden Horseshoe were Walt and his Wife celebrated their 30th Wedding-Anniversary Cafe Orleans, Blue Bayou Cafe in the PotCaribbean Ride. And so much other cool stuff to explore where Walt Disney walked around.
