I have 2 1 day tickets for both Disneyland and Disney California Adventure that I received through a contest at work. 4 tickets total, 2 tickets for 1 day at Disneyland and 2 tickets for 1 day at Disney California Adventure if that makes sense. They are one park per day, not the park hopper option.

If anyone is planning a summer trip and wanted to save some money versus buying them from Disneyland directly, I'd be happy to sell them for less than what Disneyland would charge. Picking a random 2 days (June 17-18), it looks like the cost from Disneyland would be $660. I would sell them for $450, so you're saving a little over $50 per day per ticket. They are unassigned, you can assign them to anyone you want and link them to your Disneyland account. They have a 7/31 expiry, but if you're planning a summer trip and are interested, please let me know!
