I think we stay at disneyland hilton for two nights.

So far i have booked and paid for
8-11th june jw marriott
15-17th june bevelery hills hilton
12-14th Hilton grand vacations Los Vegas.

I think i will stay at the marriott near the airport on the 4th checkout the 5th .Its only $99US per night is it worth using my catergory 4 certificate?
From the 5th i want to stay in Disneyland hilton check out the 7th. Then try for another night at JW marriott downtown and we come out of there on the 11th . Not sure where to stay yet for that night maybe the Hyatt Regency Century Plaza, most probably i will buy a premier certificate and then use 6k points to upgrade to suite if thats possible.
It seems the kids space museum is on the way driving to las vegas so probably stop in there. Im guessing the kids will like vegas they like the lights and probably crush out early then my wife can go for a play and then the next night i will hit the slots.

So rounding up im going 2 nights disneyland . 4 nights JW marriott ( la lakers / clippers game , then not sure what else to do in the area. ) then 2 nights los vegas coming back into beverly hills hilton 2 nights ( shopping , hollywood ).

Does the beverly hill hilton offer free shuttle bus to the airport , and is there a hertz , fox or any car rental places i can drop the car off nearby. It seems im going to get stung with parking and paying $40+ per day which is more than the costs of the car !
