Why It Matters
Critical CSS blocks First Contentful Paint by 2.5 seconds preventing content visibility.
How to Fix
Use WP Rocket's critical CSS feature to inline above-the-fold styles. Defer theme.css and other non-critical stylesheets. Minify the main theme CSS which wastes 10KB and has 92% unused rules.

AI Performance Analysis
This WordPress site has poor performance with a score of 53/100, indicating significant speed issues that hurt user experience. The biggest problem is an enormous 18.9 MB page size dominated by two large video files (over 16 MB combined), which is causing your Largest Contentful Paint to take 4.4 seconds - well above the recommended 2.5 seconds. The site also suffers from excessive JavaScript execution time (2.2 seconds) and blocking resources that delay initial page rendering. To improve performance, prioritize compressing or removing those large video files, minify your CSS (potential 10 KB savings), optimize images to modern formats like WebP, and reduce unused JavaScript code - these changes could easily boost your score by 20-30 points and dramatically improve loading times.
Other Optimization Recommendations
Optimize Video and Large Assets
High Impact+25 points estimatedWhy It Matters:
Video files consume 16.5MB (87% of total payload) causing the 4.4s LCP delay.
How to Fix:
Replace hero videos with optimized images or compressed WebM format. Use video poster images with play-on-click functionality. Move booking engine JavaScript (804KB) to load after critical content renders.
Reduce JavaScript Execution Time
High Impact+12 points estimatedWhy It Matters:
Main thread blocked for 4 seconds by heavy JavaScript preventing user interactions.
How to Fix:
Defer the booking engine script (causes 1.7s execution time) until user interaction. Use WordPress plugin Asset CleanUp to remove unused scripts. Replace jQuery dependencies with modern vanilla JavaScript where possible.
