Cruise spa and fitness: what's worth it

The gym is free, the spa is not. How to enjoy both without overspending on board.

ExploraGo Team· Updated September 2026

Cruise ships put a surprising amount of wellness space on board: a gym with a sea view, fitness classes, a spa with treatment rooms and often a thermal suite. The good news is that the gym and many classes are included — the paid extras are optional, and knowing which are worth it saves both money and disappointment.

The gym and fitness

Every mainstream ship has a fitness centre, and for most passengers it is free to use.

  • Cardio machines — treadmills, bikes and ellipticals, usually with a view.
  • Weights and machines for a full-body session.
  • Studio classes — yoga, stretch, spin and more; some free, some paid.
  • Outdoor tracks on the promenade or a top deck.
The gym is quietest early morning and late afternoon. On sea days it fills up fast, so go before breakfast if you want a machine.

Classes and personal training

  • Included classes are usually gentle: stretch, abs, line dancing or a stretch-and-relax session.
  • Specialist classes (spin, bootcamp, yoga) may carry a small fee.
  • Personal training is always paid and often sold in packages.
  • Sign up early; the best slots go on the first day.

Spa treatments

The spa is the big discretionary cost on board and is priced much like a land resort — sometimes higher.

  • Arrive early for treatments to use the relaxation area before your slot.
  • Tips for spa staff are usually added, as with other services.

The thermal suite

Many ships sell access to a thermal suite — heated loungers, steam, sauna and sometimes a thalassotherapy pool. If you will use it every day, a cruise-long pass can be better value than a single treatment. If you only want to try it once, buy a day pass.

Port-day offers

Spa prices often drop on port days, when most passengers are ashore.

  • Look for port-day specials in the daily programme.
  • Treatments are also easier to book on port afternoons.
  • Sea days are the busiest and most expensive times.

How to get value

  1. Use the included gym and outdoor track as your baseline.
  2. Try one included class before paying for more.
  3. Decide on the thermal suite only if you'll use it daily.
  4. Book treatments on port days if you want a discount.
  5. Say no thank you to product sales you don't want.
  6. Budget a spa limit in advance, like any other onboard extra.

Used well, the spa and fitness areas add real value to a cruise — especially on sea days. If you're planning those, see our guide to sea days on a cruise.
