Let's Rock en Seine in Paris! - Group Travel

A bit short notice for most of you maybe but I'm heading down to the city of lights next weekend to attend the Rock en Seine music festival, which is just outside Paris at St Cloud on the metro and RER. http://www.rockenseine.com/en/
I'd also like to do a fair bit of walking around the city too so I may dip in and out of the Fest. No accommodation booked yet so drop me a line if you have good budget tips! I'm a train travel blogger so I'm especially keen to hook up with folk who blog, tweet or what have you. I arrive by Eurostar around 11am on the Saturday heading back late afternoon on the Monday. Let me know if you fancy meeting up and if you're already going to the Festival. Thanks, Jools.
