The Jury's Inn, Brighton Station is a good, comfortable hotel, with great attentive and helpful staff and clean, well appointed rooms. However, the lack of a hotel car park (although, there appears to be an entrance under the hotel that looks like a car park?) is a major issue for visitor arriving by car. The proximity to the main railway station is extremely handy (great bus links, plenty of taxis etc.) and hotel patrons can use the station car park, however, one nights stay cost me £26 to park (I thought I'd strayed into central London!!) which is extortionate considering the cost of the stay. There is no discount for hotel users according to the front desk. My advice would be to either arrive by train, or use another hotel.
There were also numerous stag groups staying in the hotel, however, as we were on the top floor, we didn't hear anything of them.
