We can only holiday during the school break at Easter and definitely want to go somewhere warm enough for outdoor pools but with plenty to do/visit. We've been to Florida a few times and loved it - all of it - we don't really do the Disney thing. The other constraint is budget - we have a budget including spends of about £3.5k - which is easily doable for a beach hotel holiday I think? but we really need to do stuff and that seems to cost more. Any ideas/experiences or definite no-goes would be fab.
Sri Lanka, you could do a few sighting things, Sigiriya, Dambulla caves, Kandy Temple and local train ride. See elephants and Leopards on safari and do the beach thing. We got direct flights for £450. Great car and Driver/Guide amazing value. Cheap hotels on Booking and Agoda.
