Land at CDG 1:25 PM on an overnight from Orlando. Transfer into the city, check in, and take it easy — a jet-lag buffer evening before the wedding leg. Tomorrow: TGV to Bordeaux, then the hosts' shuttle out to the château.
TGV Paris Montparnasse → Bordeaux Saint-Jean (~2h10), then the hosts' shuttle out to Château de la Valouze (~1 hr NE, near La Roche-Chalais). Wedding runs Fri–Sun (28–30 May) with on-site lodging at the château.
Wedding, day 2 of 3. In Bordeaux — hosts have the day.
Wedding, day 3 of 3. Last night in Bordeaux before picking up the car tomorrow.
Hosts' shuttle back to Bordeaux midday; pick up the one-way rental, then a scenic transfer east through two Périgord gems: Brantôme (river-island town, abbey set against a cliff with troglodyte chambers behind it) and Périgueux (Saint-Front, the Byzantine-domed cathedral, plus the medieval old town). Reach Sarlat by evening. NOTE: Brantôme depends on an early-enough shuttle — if it lands mid-afternoon, drop Brantôme and keep Périgueux, which sits right on the A89 and costs almost no extra time. (Awaiting hosts' shuttle timing to confirm.)
Slow day: Sarlat market, Domme & the water gardens
A deliberate breather between two big days. Start on foot at the Wednesday market on Place de la Liberté — calmer than Saturday's, all local producers — coffee, strawberries, walnut cake, no driving. Late morning, up to the hilltop bastide of Domme for the Belvédère de la Barre panorama, the honey-stone lanes, and the Grotte de Domme beneath. A leisurely lunch in between, then the afternoon drifts at Les Jardins d'Eau in Carsac — lily ponds, bamboo, boardwalks under the waterfalls. Nothing more than 15 min apart; the point is to linger, not to tick sites.
The long transfer, with a Loire stop. Sarlat 07:30 → Château de Chenonceau ~11:15 (~3h45): the château and gardens, then a picnic in the grounds — terrines, cheese and bread bought at the Sarlat market the day before, fresh bread from a Sarlat boulangerie that morning. Out by ~14:30, then ~4h west to Pont-Aven, arriving ~18:30. Carnac is nearly on the line: the Mané Kerioned dolmen is a free 10-min add (~19:30 arrival); the Côte Sauvage is a stretch (~21:00, still daylight) — only if out of Chenonceau by 14:00 and feeling it. ~7h40 driving.
Wake up in the required stop. A slow morning and early afternoon in Pont-Aven — the port, the mills on the Aven, the Bois d'Amour woods the painters worked in. Leave ~14:30 for the north coast (~2h45), check in to the Cancale Airbnb ~17:15, laundry on, oysters and the port in the evening. Two-night base from here.
A slow day from the Cancale base. 20 min to Saint-Malo for the rampart circuit and lunch inside the walls (Grand Bé only at low tide — check the tables). Back to Cancale for the afternoon: the oyster beds and stalls at the port, the coastal path toward Pointe du Grouin. Nothing timed; laundry finishes.
Mont-Saint-Michel at opening — ~35 min from Cancale, be at the abbey for 9:00 before the crowds. Out by ~12:00, ~1h15 to Rennes, drop the car (VERIFY Sunday depot hours), TGV ~1h30 to Montparnasse, Paris by ~15:30. Check in to the Paris Airbnb; Eiffel Tower at night.
Full Paris day. Morning on the Île de la Cité: Sainte-Chapelle (book a timed slot) and Notre-Dame (free; reserve a slot online). Afternoon at Les Invalides — Napoleon's tomb and the Musée de l'Armée, whose WWII galleries carry the war thread the trip otherwise dropped. Evening free: a one-hour Seine cruise if it appeals.
