Bro,
I cheong Macao/ZH regularly. Nowdays, I fly in from TPE to MFM, go to Sauna (Darling) you get body rub by topless gal (very fun), some R&R (model show), rest up. Then, proceed to KTV (highly recommend new one at Hotel Gold Lion) opposite Sands, but secluded due to bridge flyover.
Rooms big, clean, and hotel rooms conveniently same floor, no need to take lift. The damage is HKD1K for two hours.
Then a round of "tea" at Hotel Lisboa coffee shop. Then only go into GongBei customs into ZhuHai (before 12pm).
At ZH, normally stay at Nanyang HaiJing Hotel's 2nd floor spa. (Its next to PoPoKo hotel) You pay RMB598 (for private room for 12 hours, plus 1 1/2 hours of full service with gal) It's economical than RMB400-500 room rate.
Then seafood next day at WanChai, its paradise there.
