Tignes and Val Thorens are sizeable ski resorts, so parking there and riding down to do the spectating may be an option. This would limit picnic provender to what you can carry on the bike, and would also mean you couldn't leave until several hours after the race finished.
Never had to drive through without a pass from ASO, but the timing for road closures seems very variable. If there's any resurfacing needs done, if will close earlier than if not. Also, you will be moved on if you're not well clear of the roadside.
Downhill sections are more empty than uphill - because you only see them for a split second - but you may see more than on TV as in recent years, there are some downhill sections where the camera bikes have pulled out as they considered the speed to be too dangerous.
I seem to remember quite a few parking up in Ski resorts and taking the lifts to near the action.
