My wife and I want to visit Provence in 2012 and are considering May to take part in the excitement and celebrity watching. Is this a terrible idea? Will it be so crowded that it will ruin any chance of a good time? We thought we might come a week early or a week late or overlap the festival by a day or two. We would most likely lodge in Nice. Please let me know if this plan for lodging and timing is a terrible idea. Assuming this is a bad idea, does anyone have an opinion of March/April vs. summer vs. Sept/Oct? Thank you.
