Yes- just no jewellery and take limited valuables. This is the only place in the Philippines I have been pickpocketed losing my cell phone to some kids some years ago. My own fault and learnt a lesson. Apart from that never had any problems. It being adjacent to Century Park makes it very handy for those staying at that lovely hotel.

Yes, I think it is safe to wander around, but I'm not sure of your level of experience in the Philippines. You should exercise some street smarts... avoid beggars at the front door, inside the mall is best, outside is a little more sketchy. Don't wear valuables, like a good watch, keep your money in a safe place. There are better malls - like Robinsons Place, which is not far away - but this one will offer some low prices and in some ways a better glimpse of "real life" in the Philippines. Enjoy yourself, for the most part filipinos are wonderful and hospitable - you just have to exercise a little caution knowing that they are the experts in their environment and you are not.

The boys have nothing to do with the parking,but just ask people to look after their cars for money. There are many cpons like that there,if you are worried,just check at the police station on the corner of the car park and they will let you know,they speak good English
