There is no self parking. You need to use there valet service for overnight parking. During the day you can park on the street. Most hotels at gaslap district require you use there valet service for overnight parking.
I would suggest that you use the ACE car park just around the corner. It was $15 per 24 hours. Some of the other car parks can be very expensive. The valet parking is $38 - you do not have to use this
