I went with my girlfriend Jacq and her family on this roadtrip, and we experienced a bit of the city's culture and local tourist destinations like hiking at Camp John Hay and souveneir shopping at Mines View Park. For dinner, we dined at the club's Japanese Bistro where a professional show chef did a mind-blowing presentation of knife throwing (the cooking knife, not the murder weapon) and fish frying.
I'd recommend you guys to come up there during the "ber" months because that's when the cold really makes you forget you're in a tropical country. The fogs are thick enough to cut with a knife, and the air is so refreshing that you'd imagine the place to be an ideal retreat spot for Christmas.
Reservations seem a bit hard these days though. I heard that December's all booked. I guess the season attracts a lot more guests than before. On a similar note, there were lots of foreigners at the lodge as well. At least the Philippines is drawing more attention to its tourism. :)
