How to sneak to Hong Kong to play alone?

For Hong Kong and Macao Pass, self-help tour, or group tour, the cheap accommodation with the group (half cheaper) is not counted as air ticket, but the tour guide fee is required. Maybe 2,, depending on what you buy, 1, is enough for nothing. Last time, I spent 5, on a mobile phone. It seems that all cheap hotels in Hong Kong are full, so I have to stay in Samsung. Otherwise, the conditions are too bad. Samsung is equivalent to a fashionable hotel in the mainland, which is very small. I have learned a lot from visiting Hong Kong and Macao on Lvyou.
