We visited Ithaa in June. We arranged to come over from Mirihi for cocktail hour (although this is now not possible for non-residents and we were luckily just squeezed in courtesy of Kat - thanks!)
Upon arrival at Ithaa we were poured our glass of bubbly and then taken down the steps to the underwater restaurant. We were there to celebrate my hubby's 50th birthday - so what a way to remember the day! There were plenty of fish around us and we got some great photos. The hosts also took photos for all of the guests. A small plate of canapes was included in the entry fee for cocktail hour. The only negative point was that it isn't a very big space (around 14 covers) so if you get one or two small children in there, as we did, it can be rather noisy and this spoilt the atmosphere somewhat. The staff also treated us to a tour around the islands by buggy, and we were even shown round a marvellous beach suite. It definitely made a day to remember for us.
