Done them both, AI three times, twice in Mexico and once in Egypt (winter hols) two weeks of chilling doing nothing, charge the batteries. Cruise last year for a special anniversary, Southern Caribbean, loved every minute of it and that was me who didn't fancy a cruise. We are off around the Med next Sept on the same ship Celebrity Eclipse. Couldn't do them every year. AI resorts, personally I think you have to get out or I go stir crazy but some people go for two weeks and never venture outside the hotel complex.
