Ok to answer you first holiday advice question.

The temp in the Red sea January will be around 71*f however this a dry heat so you get a superb tan.

As far as vaccinations go we recommend..

Typhoid Vaccination recommended 10 days before travel.

Hepatitis A Vaccination recommended 2 weeks before travel

I hope this helps

Thanks
