Two day plan for hyd?

Guys! Visiting Hyderabad with mom, dad and sister just for two days. They’re in their 60s. They’ve never been to hyd and I’ve been there a few times. Parents can’t walk long. So, I’m skipping places like Golconda and Salar jung museum. Oka roju Ramoji film city ki dedicate cheddam ani fix ayya.. can you guys suggest plans for the second day? I’m confused.. they’re into temples, shopping and historic places.

If there are better options than RFC, I can consider them as well. Please help out guys!
