Avoid the Gatwick Europa like the plague.
Stayed one night last Easter, family of 4,+ airport shuttle. Despite paying in advance they claimed to be overbooked when we arrived, kept us standing in the foyer for an hour and a half, tried to persuade us to go to their sister hotel in Brighton (for an 8am check-in!!) and finally found us a smelly smoking room at 1 in the morning.
Next day the courtesy shuttle did not materialise due to staff shortage and we had to find our own way to the airport at the last minute. No apology, nothing.
Fortunately ABC Holiday Extras who we'd booked with took up our complaint and refunded half our money, but the hassle spoiled the beginning of our holiday and we lost our prebooked seats as we checked in so late.
9 hours in the air with us and the kids in 4 different parts of the aircraft was not fun, especially as one gets air-sick.
We were possibly just unlucky but I would only stay at an airport hotel in future where I could walk to the terminal.
