I need to get from LAX to Anaheim on a Saturday afternoon. My hotel is located in Anaheim, south of the S Harbor Blvd-Orangewood Ave crossroads, so getting anywhere in that vicinity would be best. I would also be fine getting to the Convention Center and having to walk for, say, 30 minutes. I initially wanted to use SuperShuttle (as recommended here and on TravelSE) but just found out they went out of business. Most shuttle services I found cost around $100, one cost $70.
Is there any cheaper option (SuperShuttle used to cost about $20)? I am fine with public transport if available.
Edit: I do not consider this a duplicate of Alternative to SuperShuttle at LAX? because I specifically ask for cheaper alternatives than current shuttle services (i.e., < $80) including public transport.
