Since you won't call yourself a hardcore diver, I think 2 successive 7-days live-aboards is too much diving.
I think good old Shadow is right there. I've guided loads of liveaboards and to be honest there are not many of my guests that I think would be up for two back to back even if it has happened.
Better then to go somewhere where you can make daily diving in the same area as the liveaboards go. From Hamata you go out diving with the daily boats in Fury Shoal and get excellent dives everey day on dive sites like Abu Galawa, Malahi, Sataya, Maksour and Cloudio. You can also make an early morning dive on the house reef before the boat leaves and if that's not enough, a night dive after the boat returns. So it's possible to get as much dives in per day as on a liveaboard.
Have a look at my personal website WELCOME TO AZIAB for more info on the different locations.
Hope you'll have a greta holiday.
