• OTAs (Online Travel Agents) and wholesalers play an important part in getting an effective distribution of your vacation rental.
• Dedicated Channel Managers (e.g. Rentals United) can connect you (2-way) with dozens of global listing sites (distribution channels) allowing you to push availability, price (even complicated pricing models) and description (property specs) of your holiday home in real-time to these platforms.
• Specialized Channel Managers can provide you access to a support team that is highly skilled and experienced in vacation rental distribution. As they give high volume of holiday homes to listing sites, they might get faster support from these companies (compared to a PMS Channel Manager).
• PMS Channel Managers may only cover 50% to 70% of the market. Don’t rely on few touch points to reach your potential guests.
• Account Managers of spezialized channel managers will be able to recommend you those channels, that are most suitable for your marketing mix (e.g. niche sites with reduced or no commission; channels that book higher-budget and longer stay guests).
