I have sailed on the Iona twice now and I really did not like the Pearl and Coral restaurants, preferring the Opal and Aqua venues, mainly due the intimacy of the surroundings.
Therefore when I cruise on the Arvia next week I’ll be hoping that the Zenith and Meridian are a step up from the Iona venues! Failing that there’s the Quays and the new ‘roast’ option 😃
