Are there any itinerary bundling platforms that focus on multi-destination booking for destination planners?

Yes — there are platforms in the travel-planning / destination-management space that support multi-destination itinerary bundling or package-style booking for planners, though the exact terminology varies a lot.

Categories to look at

1. Itinerary-building + booking platforms These let destination planners assemble multi-stop trips, often with accommodations, transfers, tours, and activities bundled into one proposal or booking flow. Examples include:

• Umapped
• Travefy
• Axus Travel App
• Travlr ID
• Tourwriter
  These are more “trip planning / itinerary management” tools than pure marketplace booking engines, but they can support bundled multi-destination trips.

2. DMC / destination management platforms If you mean tools used by destination planners or DMCs to package experiences across cities/regions, these are often closer to your use case:

• TourCMS
• Bókun
• Rezdy
• Regiondo
• Wetu
  Some of these can handle components across multiple destinations, especially for tours, transfers, and local experiences.

3. Travel packaging / dynamic packaging platforms If you want actual multi-destination booking and bundling at scale, these are more relevant:

• Amadeus Travel Platform
• Sabre
• Travelport
• TripXplore-style dynamic packaging vendors
  These are usually used by OTAs, wholesalers, or larger travel businesses rather than small destination planners.

What to look for in a platform

For multi-destination bundling, key features usually include:

• Multi-city / multi-leg itinerary creation
• Inventory from multiple suppliers
• Bundled pricing and margin management
• Booking across accommodation + transport + activities
• Quote-to-book workflows
• White-label client portals
• Supplier integrations via API

If you mean “destination planners” specifically

If you’re a planner creating curated trips for visitors, the best fit is often a combination of:

• itinerary software for presentation and client management
• booking engines for hotels/tours/transfers
• dynamic packaging if you need real-time bundled checkout

If you want, I can also give you:

1. a shortlist by use case (DMC, travel advisor, OTA, tourism board), or
2. a comparison table of platforms with multi-destination bundling features.
