Welcome. That sounds like a good plan. Our first tandem was a 5-speed cruiser made by Trailmate. That was 30+ years ago and we are on tandem number 3 and ride every day. My stoker had not ridden a bike much since childhood and I rode a lot. It took her a while to get acclimated to a tandem and even longer to really enjoy riding on a regular basis. Now, she thinks of it as one of the best parts of every day.
Unless you are knowledgeable about fit on a bike, think about going to a local bike shop to adjust the new tandem for each of you. Being comfortable can make a big difference in enjoyment level. If you search this forum for articles on the basics of riding a tandem, you will find some good material that will shorten the learning curve on things like starting and stopping, communicating, etc.
We rode our cruiser tandem until we started taking longer rides and the maintenance became impractical. That said, it was a great way to start out and we still have fond memories of that tandem.
Post a picture of your tandem. You will find that this is a great forum where you can post questions about anything (components, adjustments, captain/stoker issues, accessories, etc.) and get helpful input.
Look forward to hearing how y'all enjoy your new tandem.
