I was recently married at Secrets Maroma Beach in January and used Styling Trio. Love them!!! But yes I did have to pay an outside vendor fee for the 2 stylists that came for the day of the wedding.
I had also wanted to do a hair and makeup trial but was worried I couldn't afford it if I had to pay the outside vendor fee for both the day of the trial and the day of the wedding, but here's what happened ...I had told Styling Trio that I was considering doing a trial on this day and time, and it was misunderstood that I definitely wanted to do it so they showed up at the resort tor the trial at the time/day I had specified (surprise lol!) and I ended up not having to pay it twice. Now whether I would have had to or not if I actually scheduled it, I cannot say for sure. I had contacted the wedding coordinator via email while at the resort to ask (it was a last minute decision) and she had replied..."When would you be expecting them?" but I didn't realize she had replied until the would be trial day and figured it was too late to follow through with it anyway, and then they ended up showing up! So worked out perfect regardless So there may be a possibility that you could go without paying if you talk to your WC (or maybe not tell them about it in advance lol, you could always fork over the money if they demand it when they show up)
