Back-to-back gym classes - bad idea?

I’ve really loved gym classes since I started doing them in January. In that time I’ve worked up from getting out of breath after some light aerobics and dance, to still having energy left after BodyCombat.

I want to get back to that properly flattened/exhausted post-class feeling, so I was wondering whether it would be reasonable to go straight from my ‘STRONG’ by Zumba class to the BodyCombat class that follows it - basically an hour and a half of supposedly HIIT, with a ten-minute break in the middle.

Relevant additional information:
- in the past I used to do a dance class a few hours after ‘STRONG’, and that was fine
- I sometimes do two gym classes in a day, but I can only do classes at all three days a week because that’s how often I’m in town. The other days act as rest days / I just walk or do some bodyweight strength work
- I can’t change to a higher intensity class due to scheduling and what my gym actually offers. I already do BodyPump on another day, and that DOES flatten me
- I have bone damage to one ankle, which will act as an early warning system if the impact is too much for my joints - I’m mostly curious as to whether there are any other factors I haven’t considered
