3. Monaco
This former Portuguese colony has grown to be one of the top gambling destinations in the world and if you want a vacation packed with glitz and glam before you have kids, this is the perfect destination. If you have deep pockets there is only one way to spend your money here and that is at the Grand Casino where you will gamble alongside the rich and famous, where the dress code is strict and the entry fees are high. Other than gambling though, Monaco offers its fair share of things to see including Monaco-Ville, a medieval village made up of pedestrian streets, century homes and picturesque buildings. There are a slew of exotic gardens to be found here, along with an art gallery, opera house and the Prince’s car collection. This is not a budget destination and thus is best done before kids, and at a time when you have some extra money to spend.
