The three-year-old steps up to 2000m for the first time in Saturday's Adrian Knox against her own age and sex and has top weight of 59kg.
“I thought it was a really good run at The Valley and she has trained on and had a couple of good weeks since,” Brideoake said.
“She will travel to Sydney, she's drawn a nice barrier (four) and as long as she travels OK I'm happy with the way she will present on Saturday.
“For the past month and a half this has probably been our plan and we think it's an ideal race for her.”
The Group One ATC Australian Oaks (2400m) at Randwick is a week after the Adrian Knox.
“We're going to just take one race at a time,” Brideoake said.
“Depending on how she goes, we'll make that call on the Oaks then.
“There is that option but whether or not we take that option up, I don't know.”
Princess Jenni is only lightly raced, having won two of her four starts and was at $7 on Wednesday for the Adrian Knox with Amangiri the $3 favourite.
“He has had a really good couple of weeks since his Mornington win,” Brideoake said.
“He will be on the truck with Princess Jenni and I couldn't be happier with him.”
