If you go to Seattle, you definitely want the sleeper. If you're only going as far as San Jose, I'm not sure -- You leave LAUPT at 10:15 AM (connecting off of Pacific Surfliner 763, leaves SAN 6:10 AM) and arrive at SJC that evening, around 8:30 PM. So it's a (long) day trip to San Jose, but another 24 hours after that to Seattle.
