River tubing experience??

We are a family of 3 just starting to plan a 6 day trip to PR in October 2021. I was interested in learning of people's recent experiences on river tubing excursions- I've read that since Maria the river is very shallow where they go and so you are kind of 'bumping along' instead of floating. Not sure if time of year would change that, perhaps October would be a better time vs. middle of summer? Any experiences (and tour recommendations if you had any) would be appreciated. We are staying on Isla Verde so looks like it will be an early morning drive if we decided to do this. Thx
