The course I play league at does not have a range at all. What I have found works best for me is to leave work a little early and go to the closest range. I get a small bucket and start warming up with my SKLZ Gold Flex (Orange Whip). That gets me loose, then I hit 5 balls with 5 different clubs. 5 shots with a wedge, 5 with an 8/9 iron, 5 with a 5/6 iron, 5 with my 5W, then 5 with my driver. Whatever balls I have left I practice chipping to different targets on the range. Then I head to the course and get a few chips around the practice green and a few putts. Then I am good to go and start chatting with other guys.
On the weekends when I play first thing in the morning and I dont have time for the range I just swing my SKLZ Gold Flex in my driveway before heading to the course. I have really appreciated the SKLZ trainer because it helps loosen you up and also helps build some strength to add distance.
