Nice itself was pretty and the locals were very friendly. That may change during July-August, but they were still smiling in the early Spring. We missed the Matisse and Chagall museums when the bus ate Tim's day pass--no big loss. The former fortifications on the east end of the waterfront are well worth the trek up the stairs. You have amazing views of the coast; all the way to Saint-Tropez.
We spent part of one day at Eze-Village, about 30 minutes east of Nice. It is a little touristy-cutesy with all the shops. However, the garden at the top of the town was well worth the €3 entry.
Then it was off to Monte Carlo. Not much to say that you don't already know: the Casino, the Bentleys and Ferraris, the mega-yachts in the harbor: yep, it's all there. At least it was a very nice Mecca-trip for me: I got to stand at the hairpin of the Monaco Gran Prix. You can keep your damn Mona Lisa, the GP is what it's all about.
