Hi JP
good luck on your course, you wont regret making the switch
As Helen said, Emporer in sharm and poseidon in Dahab all offer the usuall CCR facilities. Rifat at Poseidon will always buddy you on his inspo whilst you get some hours in if you want. Nice lad to boot as well.
Also worth a mention is Emporer divers in Marsa Alam ( Based at the Coral Beach Hotel) I went out there this month with the wife for her Birthday. Phillip the manager will happy get you lime, bottles etc for your stay. Some nice easy diving and the chance to do Elphinstone, not a bad way to get some hours in for ya.
And there are some good deals to get to Marsa at the moment, Either way in joy your course and your unit.
