I was incredibly lucky, and won a bridal portrait session--everything included! I am getting use of a bridal suite in a very nice hotel, a free bouquet, my hair done professionally, my make up done professionally, and the photography session...all for free! I won it through a social media sweepstakes, and couldn't be more excited, but what is the protocol for tipping? Am I expected to tip? Am I expected to book these people? (I already had others booked for the actual wedding!) What's the right thing to do?
