All inclusive cruises may not include these costs

• Drinking is one of the biggest expenses on a cruise ship and souvenir drinks are very good fun – they arrived in specially designed glasses which you get to keep afterwards but expect to pay way over the odds for them. • Photographs are a great way to record your experiences, but try and take the snaps yourself – the onboard photographer will cost you a fortune if you let him. Check which excursions are part of the cruise experience – usually none are and they can be pricey to pay for on top of your trip. • Gambling really, really costs, not least because small denomination tables and slot machines often don’t exist on board.
