Limitation of Acuity Scheduling - any suggestions...?

Hello

I am in a bit of a pickle here. I picked Acuity - partly because I am already with Squarespace - and also I was sure it would most definitely be sufficient for my particular business model. Then I was advised that what I want Acuity to do would not be possible on my Emerging plan, and that I would have to upgrade to the Growing plan in order to achieve what I needed.

But now it seems even with the Growing plan, I would still be unable to achieve what I need. 

I am not very tech-y and probably don't use the right words and / or phrases for certain things. But this is a summary of my issue...

• I run a textile studio in London, offering workshops and classes for children and adults. I've added our Autumn term schedule for Kids' classes and Adult workshops. So far so good!
• We also have 5 textile machines available for hire from 10am-5pm, Monday to Friday, which clients can book per day. Additionally, we offer 2-3 portable machines for rent out on a 24-hour basis.
• However, I'm having trouble overriding the machine availability in the system due to conflicts with our group class schedule. This could however possibly be achieved by creating New Resources / Rooms for each of those machines?

But then I run into another problem which doesn't seem to solvable (as far a I know)...

• As above, the booking of my group classes doesn't seem to be any issue, as they're either a one off class or a series of classes that clients book for set time. 
• But for my machine hire... I need my client to be able to block book more than one day at the time. This (to my real surprise) seems to be impossible with Acuity? 
• For some of our machines it would make no sense for our clients to just book one day. But I also don't want to force my client to have to take for example 1 week at the time. I need my client to be able to book my machine for as many days as they want and feel like thy need. This doesn't seem to be possible!

I have just take a couple of screen-shots to demonstrate -

• The first screen-shot (from excel sheet) is of 3 weeks in October from our Autumn Term schedule, which shows our group classes and events. This works fine with Acuity. 
• The second screen-shot is one of those 3 weeks, where I have demonstrated what scheduling and booking capabilities I need Acuity to achieve. And this seems to be problem / unachievable. It basically shows our group classes + our machines that are for hire with in-house and to take out.  
• What I really want is for a client to be able to - for example - choose a particular machine that he/she wants to work with, and book any number of days for that machine. 

Does anyone know of a way to workaround this? And if you think (what I suspect) that Acuity might not be suitable for my needs... would anyone be able to recommend any other scheduling platform that could handle this?

Any idea and suggestions are greatly appreciated!!
