Carnival has a great price, a 7 day out of Los Angeles, outside with obstructed view, but they are french doors that do open to the outside without a balcony for only 379.00 (5A) or as I booked for repeat passengers, I got a cabin with obstructed balcony (7A) for only $449.00 for the November 30th sailing.
This fare is on Carnival and Expedia.
Also, Carnival has a great price on an outside cabin with obstructed view in November out of los Angeles for only 159.00. The outside cabin is actually cheaper than the inside cabin and this price is for the November 17th sailing.
I did not see this price on Carnival, it was on Expedia, but if you call Carnival and tell them, they should match it.
