For me: usually lots of problems, occasionally no problems. This year's vacation appears fine, albeit nothing at the Grand Flora. RT business class to Rome via Air France (Northwest miles). 4 nights in Rome at Hilton Cavalieri (Hilton points via Diners Club) (Grand Flora not offering any rewards). 4 nights in Capri and 3 nights in Naples (Marriott Europe hopper award), and 3 nights in Amsterdam (I'm actually paying for this one).
