Having dove the Red Sea numerous times, I would suggest a definite 7 mil and a hooded vest.
Water temp at depth will be right around 70 F this time of year. Your 7 mil will compress to 3.5 or less depending on how deep you are.
Eilat is a better place to be and if you are going on a live aboard, I suggest an Israeli operation.
I used Poolster Charters, but I have no idea if they are still there.
Choose shallow easy dives that match your level of experience, it is easy to venture deeper due to the clarity of the water.
There is a reserve right in front of the Princess Hotel and is accessible only by boat. You can book a day boat to dive it, it is phenomenal.
Have a wonderful time.
