Travel is dependent on individual taste. I was less than impressed with Monaco. Outrageously expensive and really, not much there (but I'm not into racing). I have young children, so we booked the bus tour which was an enjoyable and doable way to see Monaco. There are a series of stops that the busses make. You can get off and stay as long as you wish. When you are ready to move on, catch another bus and continue the tour. The bus driver's also have speakers and will tell you about the history of Monaco, which seemed to be mostly about the Grand Prix. The casino was worth a stop, but I'm a fan of 007. Pont du Gard is 3 hours west of Monaco and that was much more interesting to me. If you want to shop, Andorra is a better option as it is not a member of the EU. It has a different VAT system and shopping there is tax free.
