Help me plan

Myself, wife, 3yo daughter and my parents will visit for 1 day. Can you please let me know few things:

(1) Where should i stay: Chandigarh, Panchkula or Zirakpur.. ghoomne wagerah ki jagah paas mein hi ho to achha hai

(2) Recommended hotels: 15k mein suite mil jaye with 2 bedrooms to acha rahega. Else 7-8k per room is the budget

(3) Important places to eat

(4) Rock garden, sukhna lake ke alawa any hidden gems worth exploring. Parents are 68 yo. so no walking type places.

TIA
