There is a lot of negativity on this board and others. Tune it out. People can complain about anything. Going to Disney is not a race and you don't have to have the perfect reservations to have a good time. You can skip
lightning lane and genie plus if you want too. Just being at
Disneyland resort, even if you didn't go on rides is fun. The atmosphere is fun. Just go have fun and don't worry about anything

. I recommend looking for the cool/ fun snacks available ahead of time and you can grab one before a long line (or a drink at CA adventure).
Also, I did CA adventure yesterday with no reservations, no lightning lane, no genie plus. I had a blast. If I was going on a busy day I might use them but you certainly don't have too.
