The
Walmart on Euclid is off the 5-freeway, which you take from the 91 freeway when you are coming from the LAX Airport.
It is right off the freeway and there is a big sign that is hard to miss.
Also, there is a really nice Ralph's Market near the LAX Airport. You can get there by taking Sepulveda South about 1-2 miles from the airport. If you go there, then get back on Sepulveda, turning right towards the airport, and turn right on Imperial Highway - the on-ramp to the 105 freeway is right there.
To get from LAX to
Disneyland Resort, you'll be taking the 105 freeway to the 605 south (about a mile) - to the 91 East - to the 5 South.
There is a post with directions & a map that you could use for reference, if you'd like. It's in a sticky thread at the top of the Disneyland Board with Faq's, etc. Click on the map thread within that sticky thread.
