Is it possible to write when in 'holiday mode'.

Ok, at the moment I am in Puerto Vallarta and the distractions are many.  Great weather here by the way.  Will I swim, go to the fish market, walk through the golf course which is 2 blocks from here and end up in the icecream shop, go for a beach walk or just sit here inside and write?  The choices are a-plenty.  Or maybe I should get on with the business of publicising and marketing my book which is why I started this blog in the first place.  How to knuckle down and work is a challenge every day.  Much to do and the days are flying by and in no time at all I will be back in a city.   Groan.
