24 days in the Philippines

Dear folks , I will be travelling in the Philippines for the first time in December. I’ve created an itinerary (copied hereunder from my spreadsheet ) and I’m wondering if I’m missing out on something. I’ve obviously never been there, but if I like the country, I will visit again. I will be travelling solo, not on a tight budget and am a fit, middle aged man. Any advice welcome .
