There're no longer shuttle buses between Gatwick Airport and Crowne Plaza Hotel, but I didn't realize it until I finally reached the bus station and was kindly informed by a local man. The hotel should have updated this information on its website; if it is just a very recent change, the hotel should have informed their guests of this! As a traveler arriving late with a big luggage, I found it pretty unpleasant.
It's not that close to Gatwick Airport. It takes 5- 10 minutes by taxi. FYI, the taxi fare from Gatwick is 12 GBP, and that from the hotel is 8 GBP (you'd better book it in the previous day).
The staffs were very welcoming and nice, and the facilities were OK.
