Hi Melin,
Thank you so much for the kind words. I absolutely agree with you about the "Rail and Sail", and I recommend it to everyone who wishes to travel from London to Dublin. Unfortunately, I did not see the Long Room and the Book of Kells.
My favourite part of the trip was when I visited the Cliffs of Moher - especially the Ferry in the Sea and watching the Magnificent Cliffs towering over me, while I was right at the front of the Ferry.
For any members planning a visit to Ireland - do not book your accommodation at Dublin only - I mean, give the trip a good 10 to 15 days, make Dublin your base for probably 4 days, please make Galway your base though (I unfortunately could not do it due to lack of time, as I had to go back to London soon), and explore the Aran Islands, Galway City, Limerick and the Western part of the Emerald Isle.
You are most welcome. I hope I get a chance to visit Ireland again - and hopefully, this time with a job in hand. Would love to settle down either in the UK or Ireland finally :)
