how about this travel agent ?

During Christmas, we are planning to go to Los Angles. LG said it would be very tired if we rent a car and drive by ourselves to tour the nearby cities, such as San francisco, etc (I know LG is lazy and easily tired). So he planned to fly to Los Angles, then join a chinese travel agent called "lulu trip", they will arrange 7 days for the group tour. What do your guys think ? I am worried that we lose fun by going with a travel group (is that for old people ?). But thinking of driving around, we must be very tired.  Also, does anybody familiar with LULU Trip, is it a good agent ?thanks a lot.
