I am not going to drone on too much about the food, entertainment etc.
Quite simply, the check in and flights from Gatwick were fine. No delays other than some clot who checked their bags but then showed up late for the flight!!
Yes the ship is old and consequently there are things that look used. e.g., where over the years, the stewards toilet brushes had rubbed the bowl, there was a grey scuff mark just above the water line. Having said that, the ship has been refurbed and the cabin wasn't noticeably more worn than say the cabin we had on P and O's Ventura. Do wish Thomson's would make it clear when a window is a porthole however.
