Throughout the 5 week ‘Eastern Caribbean’ cruise exercise classes varied in frequency.
They were held when space permitted on ‘sea’ days in the Queen’s Room (also used for covid testing) or on deck when not too windy.
Zumba was excellent with great music and held most days, as was Line Dancing. Chairobics was infrequent. I didn’t keep track, but Mareel also had some classes.
Deck 7 was open almost every day for walking round the ship etc. and only closed in extreme wind. As you may know, 3 times round the deck is over a mile.
