Please tell me the exact dates you plan to travel (departure from Glasgow and return) so I can set up a day-by-day plan with accurate opening hours and ferry/Eurotunnel times.
Do you want the overnight stay to be on the English side before you take the Eurotunnel (i.e., somewhere ~1.5 hrs from Folkestone for an easy morning drive to the terminal), or do you prefer to cross and stay in northern France the first night? Also tell me preferred towns (e.g., Oxford/Reading/London outskirts or Canterbury area).
Will you definitely use the Eurotunnel Le Shuttle (car) from Folkestone to Calais? Do you already have a booking or flexible dates? Tell me whether you need assistance reserving crossings and estimated drive start time from Glasgow.
What pace do you want (leisurely with time to relax, or packed with guided tours)? Do you want guided D‑Day tours, private driver/guide for specific days, or self-guided driving with museum visits? Any accessibility needs?
Tell me your approximate hotel budget (economy, mid-range, or boutique) and whether you prefer central Bayeux/Arromanches as a Normandy base, or staying nights across smaller seaside towns.
