Island Cruises sometimes and I believe occasionally Thomsons.
We cruised with Thomsons Destiny in June on a all inclusive package.
We had it include as an extra paying £30 per week as long as all our party of 4 were included. It was excellent value and although we were not big drinkers it was a great deal.All we did was show a card and sign for it. Most drinks were included , premium shorts and lager as well. All cocktails which were about £3.30.each if paid for. Ask your travel agent for these deals as they are well worth it.With Thomsons all tips are included as well but we still tip for the waiters and room staff.
