Vacation package from California to Riveria Maya

[gujarwala]

I'm having a wedding in Grand Sunset Princess (riveria maya) in Dec/2010. Most of us will be travelling from Canada since that's where my fiance and I are from, and its easy to search for packages with expedia.ca - you enter the Canadian daparture city, "riviera maya" as the destination and can simply locate Grand Sunset Princess in the search results which are for vacations 7 days in length.

 

I have a few friends who are interested in coming from California (they live in San Diego so would likely leave from the San Diego airport but maybe LAX if there's a large difference in price). I tried expedia.com (rather than .ca) and find it hard to use, I only get results when I enter "cancun" as the destination and I can't locate the grand sunset princess in their listing. Also I understand packages from the U.S. are usually three days in length? Is there a site that's easy to use or perhaps a TA can help?

 

Thanks.
