Mary P. Thanks for the question. Yes, your son and husband can both use their own Groupon at the same time. These Groupons are not meant to share, but in this case since you're buying two, there is no sharing involved. There is no time restriction on the use of this Groupon. That said, it's always best to book a tee time ahead of time. There will be a dedicated site where they can sign up for the lessons ahead of time as well. I hope this helps answer your question.
