Can’t recommend the Chefs Table. We enjoyed it on our NYE cruise but on our latest cruise it was like school dinners. There are so many better options on Iona, as Harry pointed out, the MDR is a much better option or if you want to splash out book the Epicurean. You’ll need to be sharpish though and book as soon as it’s available 2 weeks beforehand. As for the hairdryers, I found it no different to my hairdryer at home. I remember the days when the dryer was in the bathroom, they were usually hopeless. I used to say that my DH could blow on my hair and it would dry more quickly.
