All inclusive & lose weight?

Three days into the running blackout here in Mauritius. Our hotel is nice, the bargain price turned out to not be too good to be true. The weather is good, although to the locals it is still winter!
All we've done so far is laze by the pool or beach. We're both through a book already, can't recommend Seven Deadly Sins by David Walsh of the Sunday Times enough. The intention is to hire a car early next week, though at least two more days of laziness lie between that becoming a reality.
One of the aims of the holiday was to recover from my recent half marathon exploits & gain confidence when swimming. On our trip to Jamaica last year I suffered a panic attack whilst snorkeling. It was a wake up call, time to learn to swim. I was a reasonable swimmer in my youth, even getting a 50m badge at school, yet putting on weight as a teenager took away my confidence and I stopped swimming altogether.
In many ways the panic attack was a good thing. It made me realise I needed to confront the problem & once I was Home I registered for lessons. I've been taking weekly lessons since and although I'm in the bottom group still, my confidence is there. This holiday is the ideal platform for me to swim daily, get even more comfortable and return to my lessons with a significant improvement.
The other goal of the holiday was to continue dropping weight. Sounds perverse on an all inclusive holiday without running but I think it's possible. I've been exercising good portion control and having salad for lunch everyday. More importantly, not snacking in the morning or afternoon (though as I write this the waiter has just placed some Bombay mix in front of us!). My weight loss has been consistent recently, I'm under 14st for the first time in 18 months & with the next ten weeks being speed related I might get down to 13 & half by Xmas.
