Morgan O'Brien from Unofficial travel guides went to Discovery Cove with his extended family earlier in December and raved about it. Maybe it's a good thing that Prick and Pouty haven't ruined it with their negativity yet.
I think the issue is that they treat these long stays as a "holiday" instead of looking at them as a winter getaway and are rushing from one place to another as if they have to do everything everyday. When my parents used to go to Florida or Myrtle Beach for 2-3 months in winter, they'd find a decent condo in a complex, my dad would find a nearby golf course, and my mum would go for walks and they'd sit on their balcony and read and enjoy the nice weather. They weren't go go go every day they were there. Usually had breakfast out one morning a week with friends and then went for supper with friends one night a week. The rest of the time, they cooked at home. They maybe went to a theme park or outlet mall or sightseeing once a week. It can be done alot more chill and cheaper than what these two morons are doing.
