ASB Classic second seed and world No 18 Julia Goerges insists on the same hotel room each time she plays in Auckland and also endures questioning at customs as she tries to bring German laundry gel into the country to do her own washing.
"It brings me somehow the feeling of home," she said. "When I open my bag, I can smell home."
Both Wickmayer and Goerges are regulars at the ASB Classic but both will head into something of the unknown as they tackle the first tournament of a new season.
"It's always a bit bizarre in the beginning [of a new season]," said Wickmayer, who is the tournament's third seed. "We practice a lot, but still matches are different and it's a case of getting back into that rhythm. Some players find it the first day and others take a few more weeks. It's a new year and everyone is working hard and is ready. I hope I will find that confidence early in the season and get started."
Marina Erakovic has a great chance to do that after being drawn against a qualifier in the first round. The New Zealand No 1 was a semifinalist in 2008 but has been a first-round casualty for the past three years and wants to do well again at her home tournament.
If she can navigate her way past her first opponent, she's likely to face defending champion and world No 26 Zheng Jie in the second round.
This year's top seed and world No 4 Agnieszka Radwanska (Poland) will play Kristina Mladenovic from France and Goerges will also take on a qualifier.
Wickmayer believes she's the fittest she's ever been after a full off-season and is eager to see how that translates on the court. Even if it goes well, she's likely to let her emotions get the better of her at some point.
"I'm a girl with quite some energy, quite a temper," the Belgian said. "I will try to get the temper under control. I'm happy I have that. I prefer to have energy and be a positive girl rather than someone who is down and lazy.
"Everyone has their personality and it's nice to see on court when players show that. We are all different players and some are really calm and not really expressive and others are really expressive. I think that's nice to see."
So is witnessing a good draw.
