Hi Sue,
Thanks for your message and these are really good questions.
Generally guests all eat together, but there is flexibility with seating and your Holiday Director organises all this once on board. You will also have a welcome meeting with your Holiday Director who know all there is to know about the vessel and how things work.
With regards to excursions - there are two already included and with the optional excursions you can book these beforehand on the Celestyal Portal directly. Shortly after you booked, you should have received your booking reference to go on the portal and book directly - but do get in touch if you have any further queries with accessing the portal.
They also do have a welcome on board meeting with the HD who know all there is to know about the vessel and how things work. You can find more information about the experience via the following link: https://www.justyou.co.uk/inspiration/europe/time-to-set-sail-with-celestyal/ and if you have any other questions please let us know.
Best wishes,
Just You
