Good packing and budgeting make a big difference between a comfortable trip and an exhausting one, especially in a city where you'll walk as much as Paris.

On packing, rule one: bring comfortable, already broken-in shoes, since daily walking in Paris often exceeds 10 kilometers between sights and the metro. Layering is key, as Paris weather is changeable even in summer, and it can rain suddenly despite sunshine — so a light, waterproof jacket is essential in any season. In winter (November–March), you'll need a heavy coat, gloves, and a scarf, since temperatures can approach zero. In summer, sunscreen and a hat are worth packing; although Paris isn't as hot as the Gulf, direct sun during long walks is tiring. Don't forget a European plug adapter (type C or E), since sockets differ from Saudi Arabia.

For medication, carry a copy of any prescription you need, ideally keeping medication in its original packaging to avoid questions at customs.

As for budget, it helps to think of it in five main categories: flights (usually 1,500–3,000 SAR round-trip from Riyadh or Jeddah depending on season), accommodation (400–700 SAR per night for a 3–4 star hotel in central Paris, much less for serviced apartments or outside the center), transport (the Paris Visite pass starts around €13 a day), food (a mid-range restaurant meal runs €15–30 per person, while fast food or markets are much cheaper), and sights (tickets run €15–30 per attraction, with a noticeable discount via the Paris Museum Pass if visiting more than 3–4 museums).

Tips for saving money without sacrificing the experience: book tickets for major sights online in advance — this sometimes avoids extra fees and guarantees a slot in peak season. Have your good restaurant meal at lunch rather than dinner, since many restaurants offer a fixed-price lunch menu (menu du jour) far cheaper than the dinner menu for the same quality. Shop at local markets (marchés) and bakeries (boulangeries) for light meals instead of pricier tourist restaurants near landmarks. Use the metro instead of taxis or delivery apps — it's far cheaper and reasonably fast. And finally, avoid summer if budget is a priority, since hotel prices rise noticeably between June and August.

A reasonable daily plan for two people (mid-range hotel, meals, transit, one paid attraction) usually sits around €150–250, and it can be reduced meaningfully with some flexibility on accommodation and meal timing.
