When looking to book overnight accommodation you need to consider what factors are important to you such as cost or location. If you are just wanting a place to get your head down after a good night out then cost and possibly location will probably be top of your priorities but if you are looking for an experience that is a little more luxurious and perhaps somewhere that has a little more to offer then facilities and star rating may be more important.
It may be that you have the option of staying in a B and B or in a hotel in your chosen location, in which case you will need to consider if there is a 24hr reception if you are thinking of going out and what the checking and check out / breakfast times are. Most hotels have 24 hour reception and check in making them more accessible where as some B and B’s have a strict opening and closing time.
