CET diamond aspirations II trip question

I just surpassed seven star status for this year so I have one diamond aspirations II trip to use before 1/2017 and was wondering if I can extend my trip to include a few nights at Cosmo.

For example, the asp II trip and flight is typically for 4 nights but I want to add a 3 night stay at Cosmo so that my flight doesn't return until 3 days later.

Will the LV host book such a flight? Has anyone done something like this before? Theoretically I can double book and stay only 4 nights and spend time between both properties but I'd rather be in LV for a whole week.

 

yes, yo can fly to your destination days before, stay at cosmo, after that stay is over, check into CET for your 4 days and then fly home

 

Cool, thanks for the information.
