Excellent resort and service overall, but beware of the concierge's personal tours!:
overall, our stay at DoubleTree Resort by Hilton Penang was top-notch. The rooms, amenities, location, and staff service were all A+ grade. Hilton maintains its high standards, and we were thoroughly enjoying our trip—until we interacted with the concierge service.
Unfortunately, the concierge technically misled us into taking a personal/private trip. It ended up costing us a huge amount of extra money in damages/demurrage, which felt like a personal scam/cheating. It was completely unprofessional and left a very bitter taste on an otherwise perfect vacation.
The Hilton management seriously needs to monitor and be extremely cautious about their concierge team's activities and recommendations. Guests should be very careful when taking tour advice or booking transport/trips directly through the concierge here.
Aside from this concierge incident, everything else at the hotel was excellent. But because of this issue, I urge both future guests and management to stay vigilant.
