I agree with MalcolmAmos and Muzoid on this one,Txranger, and think that you will be surprised at just how many little "hidden" practice opportunties that will present themselves--even during the workday or out-of-town business.
You will be surprised at just how much useful and positive practice can be crammed into even a 5 or 10 minute "mini-practice" session.Especially for us beginners,Txranger,since you`re often learning more from less (i.e. correct hand/wrist technique,becoming familiar with the instrument,correct posture,etc.).I honestly believe that each and every time you pick up,hold,fret etc. you become a little bit more familar and comfortable with your instrument.I`ve also found that a productive 5-10min. episode can be some insane motivation for you to practice/play even more and makes you think bass.
Heck! Even at 3x per week of decent practicing you can make some excellent progress,my friend,so don`t even fret about that.
Best of luck to you!
