We began the third quarter on strong footing as our portfolio RevPAR ended July near $150, approximately 15% higher than June as peak summer travel translated into robust results across the portfolio.
Despite the occupancy decline, our revenue managers continued their strategy of holding rates, resulting in our comparable portfolio ADR for the quarter coming in only 1% below third quarter 2019.
Our resorts portfolio was strong again this quarter as the group generated weighted average occupancy of 68% and ADR growth of 30%, leading to weighted average RevPAR growth of 20% compared to the third quarter 2019.
The Parrot Key Hotel and Villas was our best-performing asset during the third quarter from a RevPAR growth perspective as 71% occupancy and a $409 average daily rate resulted in a $290 RevPAR, which surpassed third quarter 2019 RevPAR by 73%.
Even in the more business-oriented submarket of Coconut Grove, we were able to drive 36% ADR growth during the quarter as we captured local business from a variety of industries, law, universities, financial services, consulting, technology, healthcare and advertising, which is leading to stronger weekday demand post-Labor Day.

This performance has led to substantial weekday RevPAR growth over the last 30 days as RevPAR for our urban portfolio is up 15%, with increased demand across each of our major northeastern cities.
Our urban luxury hotels have enjoyed meaningful rate growth across the last several months, as the Rittenhouse Hotel in Philadelphia and the Ritz-Carlton in Georgetown, outperformed our third quarter 2019 ADRs by 17% and 7%, respectively.

Based on our internal projections as well as some recent third-party studies, it is estimated that 10,000 keys may be removed from inventory for the foreseeable future, if not permanently by way of demolition, resizing or alternate use conversions.

The asset management initiatives we've implemented over the past 18 months, combined with our flexible operating model and continued top line improvement showed early signs that our margin expansion goal through the recovery is moving in the right direction.

This provides us confidence in our ability to forecast post-pandemic EBITDA margin growth as our ability to drive ADR in tandem with applied expense savings initiatives, provides us continued confidence in our ability to generate 150 to 250 basis points of sustainable long-term margin savings for the portfolio.
