Only way you can practice here at wgt is by setting up a round in practice mode @ any available course,
Play Now - Stroke Play - Click on course - Change game mode from ranked to practice - choose Front/Back or 18 holes and what conditions you would like.
Then just tee off and you will get up to 0 shots per hole to do as you wish before moving to next hole.
Not the same as a practice green or fairway but it's all wgt has seen fit to allow.
Hope this helps.
