Go on a trip, do we need to pay for other projects inside? (Note: "里面的" can be translated as "inside", but it also implies something that is included or part of the main thing. In this context, I assume it refers to additional activities or services provided within the trip package.)

When traveling on a cruise, you would typically need to pay extra for services or amenities beyond the standard fare. Some examples of additional projects that may require separate payment include:

  • Shore excursions: Guided tours and activities offered by the cruise line at various ports.
  • Specialty restaurants: Higher-end dining options with à la carte menus.
  • Spa treatments: Massages, facials, and other pampering services.
  • Internet packages: Paid internet access on board.
  • Beverage packages: Additional costs for premium drinks or packages that offer a certain number of free drinks.

However, the specific extras you’d need to pay for would depend on your chosen cruise line, itinerary, and travel dates.
