Visa entry for HK & Macau

Hi everyone,

My passport require visa entry to HK and Macau. I have already applied for both visa for single entry. So if I enter HK first, stay for few days then take ferry to macau then from Macau i will take ferry directly to Hk airport to board the plane back home. Thus if I applied for single entry in Hk will that be a problem if i come from macau to board plane in hK? Does any one have any idea about this?
