It was our first Trans Atlantic cruise and we were the fourth cruise itinerary on the Horizon. Everything was wonderful. The ship is beautiful and we found it easy to navigate. The Room Stewards and Wait Staff were great - could not have done more for us. Food was excellent in the Dining Room and on Lido. Deck. In the evenings on Lido the choices were outstanding - we typically do not eat on Lido in the evenings but did so on this longer cruise. Guys Pig and Anchor food also great - no charge at lunch time although only open for lunch on Sea Days so a really good time to go is your first day upon Embarkation. Pizza was great - they will make variations of the four listings that are on the wall. Oh yes, Gelato is served daily on Lido at lunchtime - two different choices offered. We were on Deck 11 Cabin 11266 which for us was the perfect location - it is an Inside Cabin - not Spa even though Spa Cabins are further down the hall - with easy access to Lido Deck and Gym and Serenity Deck and elevators and really everything - we loved it - we were in a similar Cabin location on Vista a year ago. The evening entertainment was typical Carnival entertainment - no complaints - but similar to what we have seen in the past. The music/musician offerings throughout the ship were excellent - I would suggest there was something for everyone's taste. We had a really wonderful cruise - no hiccups for us - would not hesitate to cruise again on the Horizon.
Not sure if I chose the correct Cabin Category - we were Inside on Deck 11 - perfect location - easy access to everything - would choose it again.
