Bored at work and looking at google maps of cape Liberty.  Parking structure doesn't look all that big.  Will we have any issues getting parking?  Has it ever been full?

Can you get wine by the glass at dinner, with the dining package and what is the selection like?

Need some help please!  We have two families of 5, each with 3 kids.  Ages of kids are 10, 9, 8, 6, and two 3 year olds.  We would like to do excursions that would be highlights of the ports but nothing more than 3 hours.  I'm thinking about the hop on/hop off type excursions available.  

Any suggestions?  Would you maybe also suggest using the Private Journeys because we are a group of 10?

Thanks!
