It runs the trip as a natural arc: atmospheric and scenic first, food and culture in the middle, full beach-and-party energy at the finish. Tap the cards and steps below — every choice updates this plan live.
Tap a card to seed the route. Nothing is locked: the city sequence below can be rewritten stop by stop.
Book an open-jaw: EWR → Edinburgh in, Ibiza → EWR out. Two intra-Europe legs (Edinburgh→Paris, Paris→Ibiza) on budget carriers — watch baggage fees, they erase the savings fast.
Rent only in Scotland, pick up and drop in the same city before flying. Never a multi-country one-way rental. Paris and Ibiza run on taxis, transit, and transfers.
Three entire-place Airbnbs only — 2–3 bedrooms, A/C, 4.8+ rating, walkable to transit/nightlife. Three bases in ten days, not five. Confirm cleaning fees and flexible cancellation.
One carry-on wardrobe in layers: Scotland layers, Paris chic, Ibiza beach + night. One laundry run mid-trip (Airbnb washer or drop-off) — never on a transit day.
UK ETA required for Scotland/London — £20, valid 2 years, apply on GOV.UK a week-plus before flying. ETIAS for France/Spain starts Q4 2026 (and isn't mandatory until ~April 2027), so July/August needs no action. Keep passports valid 6+ months beyond return.
Two currencies: pounds (GBP) in Scotland, euros (EUR) in France and Ibiza. Bring a no-foreign-fee card each, pay in local currency when terminals offer a choice, and skip airport exchange desks. Keep ~€50 cash for taxis and beach kiosks; track shared costs in one app from day one.
Buy a UK+EU eSIM (or a carrier roaming pass) before departure — one data plan covers all three countries. Add travel insurance with medical cover as soon as flights are paid: the boat day, club tickets, and nonrefundable Airbnbs are exactly what it protects.
Do not pay until the group has locked dates, route, budget ceiling, passport status, and luggage plan. Price the whole route with bags before comparing budget carriers.
Six decisions, six colors. Lock all six and the group-chat message below writes itself.
