请教西加勒比海线路的选择

初次准备尝试邮轮，在smartcruiser比较了下7-night Western Caribbean Cruise， 出发日期为1.21或者1.22准备都选内舱。请大虾们指点下：

1.关于线路的选择
除了海岛外，我还是想多看点人文和历史的景点，尤其是不想划过Maya遗址，所以请帮忙看下，以下哪条线路比较好。

2. 以下的线路是不是只要有美国多次往返签证就可以拉？

3. 准备从Los Angeles飞佛州上船。上船点的选择除Miami外，其他几个港口Tampa，Port Canaveral,Ft. Lauderdale 是否有机场或者从Miami、Orlando过去很近？
