All the clubs in Macau would surely welcome single customer.
China City has a large lobby where you can sit with girls, but you would encounter many people walking pass by you if you don't mind. But then you may probably be the only customer sitting in that area as people usually prefer to have private room unless it's a full house. If you request to sit in the lobby, you'd get the same service as in any private room, except no karaoke and you cannot take off the girls' clothes in public
Those package prices are varied from different time slot, all packages include round-trip ferry ticket, basic charge such as fruit plate and nuts, some standard drink such as a few cans of beer, the time cost of girls sitting with you in the club and going out, and usually one hotel room for two hours. While overnight package would include a hotel room that you can check out the next day at noon. There is also one difference as some clubs offer dragon package (龍) that has already included the girl's service fee for your "close encounter" within the hotel room. Otherwise, you'll have to pay the girl $1,100 for one shot and $2,200 for two shots, plus one or two hundred tips to the girl; but for model, you'll have to pay a few hundred more. Anyway, you can always ask the manager or mami at the club before taking the girl out.
Since you've been to Macau sauna before, seems like you'd be quite familiar with the process of getting package ticket at Shun Tak. So my advice is just bought a package ticket at Success Travel Agency at Shun Tak for China City (doesn't matter if it's a "dragon" or ordinary package). Upon arrival, request to sit in the lobby. When the manager / mami comes, ask them to explain the whole procedure to you once. Since you speak fluent mandarin, you should have no problem to communicate with the staff and girls at the club at all.
