My wife and I will be in France from June 28 until July 14, 2022. The core of the trip is to see KISS (my favorite band) in Nimes at the Roman Arena on July 5. So we built a few days in Lyon and Chammonix and a week in Provence before 1.5 days in Paris then flying home. In the meantime, the Rolling Stones (my wife's favorite band) just announced a European tour in June/July. The only feasible show for us is in Brussels on July 11. It actually works out reasonably well as we can cut Provence short by 1 day and TGV up to Brussels, then TGV back to Paris the next day as originally scheduled. I know things can change in an instant, but are there currently any restrictions for entering Belgium from France via the train? Also, the show is at King Baudouin Stadium so we will likely stay across the street at Hotel Expo. Is that area ok for 1 quick night?
