I was a travel companion for my mother who was tetraplegic due to MS for over 20 years. I worked in rehabilitation and SCI care for 40 years before recently retiring. I have been a moderator on this forum since 1997. I LIVE in San Diego (native), and do not like to see my city mis-represented nor incorrect information posted about it on our forums. The OP is FLYING to San Diego...not LA or Orange county and taking Amtrak. He is not asking how to get to Legoland or some other north county destination that he could get to on the Coaster. The information you gave about the San Diego Trolley (light rail) is incorrect. Get over it.
