They're both nice, each with plusses and minuses. Cassine Station is really cool looking and the balconies are large and private. The "martini deck" has fabulous views of the gulf. It's new so everything is totally up-to-date. On the minus side, you have to cross the street (though the beach access is directly across the street and easy as pie to get to). Emerald Hill is beach side and if you get one of the units that's beach front and on the ground floor, you'll have a nice grassy area to spread out on. On the other hand, it's an older condominium so some of the units might not be as renovated as you'd like. Emerald Hill is a bit closer to Seaside.
