My family of five is going to Disneyland on Monday and we have park hoppers so we'll be napping at the hotel after lunch and going to California adventure in the afternoon. Radiator Springs racers is a must for my six-year-old son. I have 2yo and 4yo daughters so waiting 60min+ is not ideal. So I'm wondering what my LL single pass strategy should be: should I purchase the lightning lane 1st thing in the morning when I get into Disneyland or should I wait until the afternoon to purchase it once I'm actually in California adventure? I did a quick search on the reddit and didn't see this answered.
