I will say that not having a Park Hopper for a 2-day trip is fine. There is plenty to do in both parks, and plenty to eat, so you really don't need to hop. We did a 4-day trip one year without park hopping to save a bit of money, and it was fine. Now we do often park hop when we have the option, so I do agree with others that it is nice, but I disagree that it is essential. Especially since this is your first trip, so everything you do will be your first time doing it. There's no way you'll find that you've done everything. Ultimately it's $20 more for a 3-day non hopper than a 2-day hopper. So if you really wanted extra time at
Disneyland (and were willing to spend the money) you could get the 3-day non hopper and go to Disneyland the evening you arrived rather than trying to park hop your final day.
