We loved the Arora Gatwick! It was beyond what we expected for an airport hotel. It was in a quiet neighborhood that it was very restful, but had quick airport shuttle service. We actually went back the following week when our travel plans changed, simply because it was so comfortable there.
We have found that the Copthorne Hotel provides us with a final bonus to our trips to visit relatives in England. We return our rented car to the airport, check in to the hotel for a final night in pleasant surroundings, and catch our return flight home without the anxiety of trying to do it all the day of our return. The peaceful atmosphere of the hotel gives no indication of its closeness to Gatwick airport.
I have to say if our experience was anything to go by then the return after the holiday was not as good as the way from the hotel. My mobile phone had run out of charge on holiday and stupidly i had not taken a charger however I assumed we would be able to easily contact the taxi firm from Gatwick after collecting baggage. Unfortunately there were no public phones working at the airport and non of the other taxi firms who have "offices" within the airport building would help other than to charge £16+ for the lift to Effingham Park. None of the "booked" taxis would phone to base to get a taxi to come and pick us up. We were warned that it would have been a hours wait for a taxi, had we been able to phone for a car anyhow. We resolved the problem ourselves in the end but it was not easy and cost a lot more than the £11 it should have..
Crawley is in West Sussex, and a main center of industry and employment approximately midway between London and England's south coast. England's second-largest airport, Gatwick, is located north of town.
