I haven't smoked now for 3 months and it was our trip to Florida last year that made me feel as if i cant do this forever. It started at GAtwick with all smokers being designated in this square area with fans inside, i felt such an outcast. Then in the parks i was constantly looking for an area to smoke with my husband tutting behind me. I now can go next year free from smoking.
I cant answer your question on resorts as we stayed off site but it was a worry to me before we went last year wondering wether i was going to go ages with out a ciggerette. I never found it a problem finding areas to smoke and i would think that the resorts would be the same as the parks. I just found it slightly embarrasing having to go off in a little area to have my hit.
Good luck
Have a great trip
