Good morning everyone. My name’s Ethan and I’d like to tell you about the different activities on offer on board this fantastic cruise ship.

First of all, there are lots of sports facilities. There’s the swimming pool on deck 3. I’m sure you’ve seen it already. Near there, there is a hot tub, sauna and steam room. You can use the pool and hot tub between seven in the morning and eleven in the evening. The sauna is available from one in the afternoon until nine in the evening. You don’t have to book or pay extra to use any of these facilities.

There’s a gym on deck 4, and you can go there whenever you like. No need to book. It’s open from 6 am until 10 pm. There are also four squash courts. You can book these at the desk in the gym.

If you’re not sporty, there are lots of other interesting things to do. If you’d like to learn to paint, there is an art class every morning at ten o’clock, which lasts two hours. There’s a cooking class every afternoon at three. There’s a different theme every day. Today it’s Indian cooking, and tomorrow it’s Italian cooking. You don’t have to book for these classes, just arrive. But there is a maximum number of people in the class, so make sure you arrive early, or there may not be enough space for you.

In the evening we have lots of entertainment on offer. There’s a show every night in the theatre. Tonight there’s a jazz band, and tomorrow night there’s a comedy show. These shows are all free, but you need to get a ticket from the ticket office at the theatre. In the afternoons, you can hear lectures about the different places we visit on the cruise. Today, there’s a lecture about the wildlife of North Africa. This is at two o’clock and four o’clock, in the theatre. It’s the same lecture both times. Tomorrow’s lecture, which is at the same two times, is about the Roman Empire in North Africa.

So, that’s all for now. On Wednesday, I’ll tell you about the different activities happening later in the week. Until then, I hope you have a great time.
