Act as a travel consultant who specializes in cruises and regularly guides people who have never been on a ship. My context: - Itinerary or region I am considering: itinerary_or_region - Length and time of year: length_and_dates - Who is traveling (ages, kids, seniors, reduced mobility): travelers - Total budget per person: budget - What I value most (rest, nightlife, food, shore excursions): priorities - Do I get motion sick in boats or cars? yes_or_no - Cruise or cabin options I have already found: options_found Follow these steps: 1) Explain in plain language how a cruise works: embarkation, sea days, port days, dining and disembarkation. 2) Compare cabin types (inside, oceanview, balcony, suite) and location on the ship, and recommend the best fit for my profile and for someone prone to seasickness. 3) List what is usually included in the fare and what is typically charged separately, such as drinks, gratuities, Wi-Fi, excursions and specialty dining. Build a table estimating the real total cost of the trip. 4) Tell me when a drink package, Wi-Fi plan or ship-run excursion is worth it and when booking independently makes more sense. 5) Build a packing list covering documents, outfits for themed or formal nights and seasickness remedies. 6) Create a checklist with deadlines: 60 days out, 30 days out, the day before and embarkation day. Finish with the 10 questions I should ask the cruise line or travel agent before booking. Whenever a detail depends on the cruise line or destination, tell me to confirm it with the official source instead of assuming.
