I would not reccomend staying there unless the price is truely right. IT is right near my house, and it is a very residential area that is about 15-30 mins. by car away from most of the local tourist attractions. The only reason the hotle is even there is becase there is a large Nokia facility right up the street and it caters to the buisness travellers.
Legoland is about 45 min. away from San Diego depending on traffic and from what I hear the drive is worth it if you have young children. Hope this helps!
