What is ancillary revenue ?

Hotel ancillary revenue is the income a hotel generates beyond the basic room rate. It can come from room upgrades, early check-in, late checkout, airport transfers, breakfast, restaurant bookings, spa treatments, parking, excursions, activities and other destination experiences.

Seasonal Hotel’s Revenue Challenge

A seasonal hotel has something an all-year property does not: a deadline.

If you are a seasonal hotel owner reading this article, you probably already know the struggle. Every year, you have a limited number of months to make the season work. You need strong occupancy, the right room rates and enough demand to maximize the few peak months that generate most of your annual revenue.

Even when you reach high occupancy, there is another challenge: how do you make the most of every guest while they are already staying with you?

For many seasonal hotels, especially in destinations such as the Greek islands, the operating window can be short and highly concentrated. A great season this year does not automatically guarantee the same results next year. Demand changes, competition grows, travel behaviour evolves and external factors can affect an entire destination.The scale of this challenge is significant in Greece. The country had 10,118 hotels in 2025, representing more than 450,000 rooms and 900,000 bed places nationwide. At the same time, seasonality remains particularly strong: hotel occupancy reached 77.2% in July and 81.3% in August, compared with just 12.7% in January according to ELSTAT.For a seasonal property, this creates a simple reality: once those peak months are gone, the opportunity is gone with them.

The Revenue Opportunity Beyond the Room

Once your hotel reaches high occupancy, increasing revenue becomes harder if you continue looking only at room sales. A seasonal hotel has a fixed number of rooms and a fixed number of nights available before the season ends. When most of that inventory is already sold, the next opportunity is not necessarily finding more guests. It is increasing the total value of the guests you already have.

Think about one confirmed booking. The guest has already chosen your property, committed to travelling and shown a willingness to spend. During that same stay, they may also need an airport or port transfer, a better room category, breakfast, a spa treatment, dinner, an excursion, a rental service or late checkout. Each of these services can increase hotel ancillary revenue without requiring another reservation.

This is especially relevant for resorts and seasonal properties because many already offer products that go far beyond accommodation. The problem is often not the lack of services. It is that guests do not always know they exist, or they discover them too late.

A traveller may never visit the spa page on your website. They may arrange their airport transfer with another company before arriving. They may book a boat excursion through a third-party platform or choose a restaurant outside the hotel simply because your own experience was never presented to them.

In these cases, the guest did not necessarily reject the hotel’s additional services. The hotel may simply have missed the opportunity to present them.That is why ancillary revenue is not only about creating more products. For many seasonal hotels, the first step is making the services they already have more visible, more relevant and easier to purchase throughout the guest journey.
