From the first conversation through your return home, you have a real travel advisor helping coordinate the details and supporting your journey.
Meet your travel advisors
Every Sirena Collective inquiry is handled personally by Karyn Pavich or Tanitra Partivit. You will work with a real advisor who takes the time to understand your preferences, priorities and vision for the trip.

Co-Founder · Luxury Travel Expert
Tanitra designs custom luxury vacations with an emphasis on memorable hotels, immersive experiences, groups and multigenerational journeys that feel personal rather than prepackaged. Her approach balances beautiful possibilities with practical details.
What we plan
From private celebrations and multigenerational vacations to corporate retreats, luxury cruises and yacht charters, Sirena Collective designs complex travel with the details handled thoughtfully from the beginning.
01
We plan family reunions, milestone celebrations, friends' trips and multigenerational vacations with different ages, interests, room needs and activity levels in mind. The goal is a trip that feels shared, not a group negotiation conducted in twelve separate text threads.
02
We help companies plan destination retreats, leadership gatherings, incentive travel and team-building experiences. Services may include hotel sourcing, group accommodations, meeting spaces, private dining, transportation and memorable local activities.
03
We arrange private yacht charters for families, groups and celebrations, with particular interest in Croatia and the Adriatic. We help match the vessel, route, cabin configuration, crew and onboard experience to your group.
04
We plan across luxury, premium, expedition and family cruise styles, including Ritz-Carlton Yacht Collection, Explora Journeys, Four Seasons Yachts, Orient Express Sailing Yachts and Royal Caribbean, along with other cruise partners selected for your travel style.
05
Honeymoons, anniversaries, birthdays and once-in-a-lifetime gatherings deserve more than a string of reservations. We create a cohesive journey around the people and occasion being celebrated.
06
We plan complex itineraries across multiple cities, islands or countries, coordinating hotels, transportation and experiences while keeping the pace enjoyable and realistic.

Planning questions
Helpful answers about custom travel planning, cruises, private yachts, corporate retreats and multigenerational trips.
A luxury travel advisor helps match destinations, hotels, cruises and experiences to your interests, travel style and priorities. Sirena Collective also helps coordinate the practical details so your trip feels cohesive rather than assembled one reservation at a time.
Sirena Collective is compensated by many hotel, cruise and supplier partners. Some highly customized itineraries, destination research, corporate retreats or complex group planning services may require a professional planning fee. Any applicable fee will be explained before work begins.
We work across luxury, premium, expedition, river and family cruising. Depending on the traveler and itinerary, this may include Ritz-Carlton Yacht Collection, Explora Journeys, Four Seasons Yachts, Orient Express Sailing Yachts, Royal Caribbean and other cruise partners. We compare ships, suites, routes, dining, atmosphere and onboard experience instead of assuming one cruise line fits everyone.
Yes. We help travelers compare Ritz-Carlton Yacht Collection itineraries based on season, ports, time in destination, sailing length and the experience they want onshore and onboard.

Exact inclusions depend on the vessel and charter agreement.
