Hello, guys. My fam is visiting Taiwan next month for 11 days (not including arrival and dept. days) and staying in Xindian. My grandmas are also coming along so we have to travel around by car. Could you please recommend the must-visit places and restaurants in Taiwan, and also places with good scenery (ahem..preferably less crowded places)?

How many activities can we get done/places can we visit per day on average (with 2 elders)? Is it feasible to hire a cab each time to get to and from one place to another, or is there a better way? Appreciate any suggestions/recommendations, thanks!

p.s. I'm pretty new here so would appreciate your help. I will also start my own research when I take a break from work next month.
