On our Equinox cruise in March, they had a similar pre cruise offer, which we considered, but decided to wait until we’re onboard to see the actual schedule. The app (pre cruise) was showing hit classes 5 of the 9 days. When we boarded, we headed to the gym, and found that they had a different exercise class plan which offered HIIT classes only 3 times (one which was late afternoon) and then offered various yoga and spin classes throughout. The schedule did offer a 7 am stretch class each morning (no charge), and then some type of class most days at 8 am and 9 am. Classes are $10 per class. They did have a cruise pass for all classes for $100 (9 day cruise), which was discounted to $90 on boarding day, which we bought. We managed to squeeze in enough classes to just break even, but only two were HIIT. I think in hindsight, we would just pay as we go…..we did our own HIIT workouts some days when the studio didn’t have classes happening.
