Wendyg,
Holiday Inn is very new. Near to Mahkota.
If u want super convenient location, will recommend Equatorial Hotel. Service ok but hotel is furnishing is quite old. 5 min walk to Carrefour, 10 minutes walk to the Peranakan restaurants. Everything is within the vicinity.
They give u RM88 rebate where u can eat anything u want within the hotel. If not fully utilised, will return 50% of remaining in ringgit.
For Holiday Inn, must cross main road, so with kids, a bit leh chay. Need to walk some distance to find traffic light. However, it's brand new, less than 2 years old.
Would advise u to go for Marriot. It's located on the other side of the town. So where ever u go, need to travel by taxi. But recently renovated.
