Thank you, Allison. Good morning all, and welcome to OneSpaWorld's Second Quarter 2021 Results Conference Call. The second quarter represented a terrific start to OneSpaWorld's resumption of service at sea and continued positive momentum across our destination resort spas that have reopened. While we continue to operate in a fluid environment, sequential revenue improvement from the first quarter was significant.
In total, our second quarter results mainly reflect the performance of our destination resort spas. Of the 14 ships in service at the end of the quarter, 10 resumed operations in June. That said, our intense focus and successful implementation of our actions to ready our staff and health and wellness centers to safety, often led to a flawless execution of our new protocols and outstanding service by our highly dedicated staff members.
I would like to thank our crews and destination resorts spa staff and corporate teams for enduring endless hours of training among many other hardships to support our outstanding return to service. We expect to build upon our favorable momentum as more ships return to service during the second half of the year.
Turning to highlights of the quarter. Total revenues were $9.2 million and mainly reflected destination resorts spa revenues. Adjusted EBITDA was a loss of $9.7 million. Of note, our destination resort spa has generated positive EBITDA in the quarter, and we are increasing staff at almost all locations to meet higher-than-expected demand, and we ended the quarter with total liquidity of $54.8 million.
As of yesterday, we operated on a total of 42 cruise ships, 7 more than we estimated when we reported first quarter results in May. While occupancy and stopping are below historical levels, we are continuing to see strong customer demand and spend for our services.
To this end, in the month of July, customers spent exceeded July 2019 levels onboard the cruise ships that we sailed. This was accomplished despite lower than historical promotional activity. We also are encouraged that recent prebooking statistics are up versus 2019. In keeping with OneSpaWorld's tradition of supporting our onboard staff, our corporate team has already visited 30 of the 42 ships that have returned to service to ensure we generate the highest possible revenue, while maintaining the highest standards.
Flawless return to service is our top priority. We successfully placed 779 cruise ship personnel on vessels at the end of the second quarter for actual and anticipated voyages, overcoming the challenges of the pandemic, securing visas, COVID testing and other travel restrictions. Despite these hurdles, our team members are ecstatic to be back at sea.
We are adjusting our plans on a daily basis so that we are in a position to react immediately to any additional unplanned return to service. By the end of September, we expect to have 1,383 staff reembarked on vessels. We believe we are well positioned to continue our flawless execution as we welcome staff back and prepare to resume operations on an additional 37 ships by the end of September.
We were also delighted to see the U.S. government approved sailings in Alaska, which represents an important market for us, generating some of our best operating metrics. We believe our initial return to service performance confirms that we are positioned powerfully to capitalize on the strength of our team, operating platform and business model to drive long-term profitable growth as cruise ships and destination resorts spa operations fully resume.
Overall, we will continue to execute with intense financial discipline, while implementing strategies that enable the company to not only return to peak levels of sales and profitability but also elevate our brand and further expand our service offering in our ongoing efforts to increase value for all our OneSpaWorld stakeholders.
With that, I'll turn the call over to Stephen, who will comment on our second quarter 2021 results and liquidity position.
Stephen?
