My current plan is mid march. 4 days. non hopper tickets. (This will be spring break season, so I anticipate busy)
The plan was simple in my head: 2 days for each park. Done.
But, people are mentioning to me that I should do 3 days in DL and 1 day in CA adventure. Is one day in CA enough?
Mid March is usually busy and Food and Wine Festival will be going on then, making CA a lot busier than normal, especially in the evenings.
Also, I do have the option of staying one more day in the area, would 5 days in DL be too much time
It would for me, but it depends on what you want to do while you are there. If you want to see every show, take a tour, go on every ride, eat at every table service, you can keep yourselves busy that whole time.
Parkhoppers are extremely valuable and I'd get those and budget less on something else. I cannot tell you how many times I've been to one of the parks and it was too crowded for me to enjoy myself, so I escaped to the other park. Maxpass is also very helpful, but only buy it a day at a time because you won't necessarily need it every day. If you want to ride all the headliners in DCA and don't have early entrance (a perk of staying onsite every other day), MaxPass can be a necessity. Standby wait times will be 90+minutes for each ride.
Another helpful hint, if you all don't mind riding in different cars is to do single rider at Radiator Springs. I've never waited in the regular line there because it's way too long for me. Personally, most of my favorite rides are in DCA. My favorite restaurant is in DCA - Carthay Circle. I like everything else better in DL as far as theme and just hanging out or looking for turtles in the pond by the Adventureland sign.
If it were me, I'd do the 4 days with parkhoppers every day and add MaxPass on 1 or 2 days that I wanted to be ride heavy days.
