Staying at Grand Calif Hotel this summer..What Marriott "beach" property?

[jerseygal]

Excited about booking our 4 night vaca at Grand Californian Hotel this summer...First time in California..

Looking to head to San Diego area for 3 nights..Have Marriott Points that we want to use..

After researching, San Diego Marriott Marina looks to be the best for our needs..Will have a car, so we plan to head to Coronado Island one day for the beach(by the Del) and LaJolla one day....

It seems that alot of hotels in SanDiego are effected by a train.....Coronado Island Marriott looks nice, but the reviews point to musty rooms..Have mold allergy so that won't do...

Any other suggestions for a beautiful Marriott instead of San Diego Marriott Marina...Marriott Dana Point looks nice, but I think there is more to do/see in San Diego..

Thanks for any suggestions..Can't wait to go!
