There are rental weeks available in Redweek for 2 bedroom units in July for the following resorts, depending on how much you want to pay:
Marriott's Newport Coast
Carlsbad Inn Beach Resort
Hyatt Residence Club Carmel, Highlands Inn
Four Seasons Residence Club, Carlsbad
Grand Palisades, Carlsbad
There actually seems to be a lot of availability. You might want to take a look. These are just the first few I found.
