Staying in Belfast ???
Any tours of Ireland should definitely include Belfast.
If you are visiting the city then a suitable hotel is important to enhance your enjoyment.
The Europa hotel is in Great Victoria Street and is a super spot. The lounge bar allows you to watch the world go by. The famous Crown Bar is only across the road and the Guinness and food there are superb.
Remember hotels are a little like houses LOCATION LOCATION LOCATION
The Fitzwilliam hotel is just along the same road though the atmosphere is much more sterile and there is no hustle and bustle.
There are other options but the central location of these two allow you to walk to the City Hall , Grand Oprea House , Queens University , as well as great restaurants and pubs.
There are many great shops within walking distance such as Chinacraft http://www.yelp.co.uk/biz/china-craft-belfast , Gardiners Jewellers http://www.gardinerbrothers.co.uk/ , the Wicker Man http://www.thewickerman.co.uk/ , and the fantastic new Victoria Square http://www.victoriasquare.com/
Remember Ireland tours need to take in Belfast and your hotel needs to be the right choice
You can of course avail of many Belfast tours of the city and beyond.
