Dear [Friend's Name],
I hope you can join me for the Kuantan Heritage Tour this weekend. We'll get to see beautiful nature spots like the Endau Rompin National Park and learn about local culture like the traditional dances at Taman Budaya Pahang. It's also a great way to experience the lively city. Let me know by tonight if you can come!
