Average Hampton and they Nickel and Dime families
Stayed at this Hampton Inn for 8 days in May 2012 to visit SD sights and family. The first shock was that when I asked for a crib they wanted to charge me $10/day and then another manager relented and said that cribs are no charge but extra beds are. 
Unlike other Hampton Inns I have stayed at, they don't have microwaves or refrigerators in the rooms as standard. You need to order them for another $10/day for each. When I told them that I have never had other Hampton Inns charge me for these appliances, they said, "Well, since you are staying a whole week we will only charge your $10 for each for the week" I said "Well OK..." but still a annoyed. If they charged me $10 per day, I could have bought one for the week.
Except for a few employees (Maria in the breakfast area - you are great!), the rest of the employees do not have a smile on their face and seem unhappy. Pool is small but adequate.
Beware that right now they are doing construction around the hotel that starts around 6am and you can hear it from the rooms.
I would not go back to this Hampton Inn, just because they nickel and dime you, however, it was convenient for us to visit family in Vista and go to Legoland and Sea World.
