There is no doubt that a good makeup artist and hairstylist are key components that contribute to the quality of the photographs as well as to the overall experience of your wedding day on the whole.
Having the hair and makeup team reach the client in her hotel and take care of bridal makeup and hairstyle in a way that will look good in images (this is slightly different from usual make up) gives a hust boost to image quality (and saves post production time and costs) may it be to a destination wedding or any big day.
There is another contribution to the overall experience of the client: being able to relax and be in a good mood because someone is taking care of his/her beauty is beneficial.
There is always a make up artist present at large weddings. Even for elopements and for pre-weddingor trash the dress sessions, I recommend considering hiring one for your big day.
It is a great way to capture beautiful images during engagement and portrait sessions, but brilliant results can be achieved without it as well.
I typically provide a list of endorsed professionals located in Venice to clients that book my services as it is important that besides the professional qualities there is a match in style.
Like for pictures and many other aspects of life besides the general level of quality the "good vibes" should match in order to create a great experience.
Even if you opt for a sunrise photo session, some makeup artists will still be available for you to use.
