Anywhere we can leave bags?

Hey guys, Hope the fires are getting under control and this ordeal ends for you all. I'm coming with family for a 8 night holiday in late Feb. Four of these nights I'll be living at a hotel in Anahiem near Disney. But on the last day, my flight from LAX is at 10 pm and the hotel says they don't have a place to store bags for us. I couldn't find anything at the airport as well.

So I'm confused what to do, I don't wanna waste the entire day just lugging around bags with kids. Any ideas?

Ps. Also if you could suggest a good area to look for hotels in LA city. We wanna see Hollywood walk, Santa Monica pier, Universal, Warner Bros and maybe a museum..

Thanks ans stay safe ..x
