Any one done both and if so which is your pick and why? I am watching the weather reports and it looks like the Eastern is sunnier and less rainy compared to the 10 degree difference with the Western and cloudier forecasts? I am beginning to second guess myself ?
Have done both eastern and western many times and find the ports in the eastern Caribbean more appealing. Jamaica, Cozumel and Belize just don't do it for us, although Key West and Grand Cayman are worth visiting. Also, we find the weather in the eastern Caribbean to be more reliable - temperaturewise and rainwise, especially during the winter months.
I've done both itins a number of times as well, and haven't really noticed any difference in weather.
The western itin is the more active.. better snorkeling, and water sports etc.
The eastern has some wonderful beaches, and is known for it's shopping (Though you had best know your prices if you're shopping for anything of value).
