Aliso Viejo is in south Orange County (John Wayne airport). Long Beach certainly has schools, but that would be a long drive, and Carlsbad / Oceanside in San Diego County would also have schools, however this may be an easier drive.

John Wayne Airport, Airport Way, Santa Ana, CA is 15 miles away via the toll road. Very easy drive.

2198 Palomar Airport Rd, San Diego, CA 92008 (Carlsbad Airport) is 46 miles with relatively light traffic. Oceanside airport is slightly closer, and does NOT have an ATC tower, if that is important to you.

Long Beach Airport, 4100 East Donald Douglas Drive, Long Beach, CA 90808 is 36 miles of some of the worst traffic in the world.

Certainly folks will have opinions on part 141, but I don't. If you like a structured learning environment, then this is a good idea. Otherwise, there are lots of good options.
