My suggestion since u are having so many days:
1st day - Get a reasonable hotel in Macau..probably contact the same guy that I pmed u b4 (But dun choose the New Century hotel in Taipa island (Pretty far from Macau Peninsular) Get those hotels closer to Senado square & etc
2nd Day: Continue sight seeing in Macau (Spend more time out of the historic enclave..probably to Ah Ma temple, Maritime Museum or even take a Public bus to Taipa/ Colloane island...ehhhh now already becoming one after they built the Venetian Casino in the middle of the strait
end of 2nd day...Check-in to Yong Tong Hotel (RMB230 - on top of Zhuhai bus terminal/ KFC) or the closer to the border (Jingye hotel (RMB190)...shop till u drop at the underground Gongbei gigantic Landmark shopping complex. thereafter continue to Lian Hua lu..street shoppings..lotsa ladies & fashion related stalls here..(~2Km long & 1 big loop back to Gongbei border....be prepared for leg cramped!)
3rd day..probably take a taxi or local bus to the the lady of the sea statue & also the sea park along Zhuhai..Thereafter check-out & buy afternoon bus ticket to Guangzhou (Super VIP bus =RMB75) - 2.5hr to Guangzhou Tianhe bus terminal (i.e opposite the gigantic Tianhe stadium) ..U can either look for hotel around this biz district & thereafter continue to shop at the Teemall & adjacent Granview mall (One of the largest in the world - for me smaller than Sunway Pyramid
)
4th day....take the super efficient Guangzhiu underground MRT to all the tourist attractions in Guangzhou such as Chan Clan House, The emperor museum & the famous park opposite the museum, Guangzhou Pagoda, Guangzhou mosque, & must not be miss the Beijing Lu shopping...If more time, probably another MRT ride down South to Updown 9 road (San Sia Chiew Lu) shopping street, Collonial island of Guangzhou
End of 4th day - take the MRT directly to the Guangzhou East railway station (There are 2 railway stations so pls dun confuse - This East one going to Shenzhen. The main station goes to other part of China) - 1hr to Shenzhen & experience the 200km/hr ride on the speed train that pawned our ERL!
Check-in to Railway station hotel on top of the railway station itself (RMB200/nite). Shopping at the opposite but joined border shopping complex..
5th day - Take the shenzhen MRT to Window of the world/Splendid china or even shopping at Dong Men street. Mid of 5th day cross over to Hong Kong Stop at Mongkok station & - SHop at Lady /Tung Choi st (They opened Mid-day till late at nite), Probably check-in to your hotel at Mongkok (Chk recommendation in HK thread). Goto Temple st for nite shopping
6th day - Check-out & take the MTR to the Tsim Tsa Sui east station...and visit the Arena of Star (Something like the Hollywood walk of fame...take lotsa picture & spot all your famous actors & actresses feet/hand prints!...See the whole Hong Kong island from the arena of Star. Mid day, goto the Peak at Hong Kong Island & view Hong Kong from the top of the peak. Evening - take the ferry to Macau & check-in to New Century Hotel (~2km from Airport)
7th day-- Bye-bye to Pearl River Delta
