Living and working at NSGB is not, however, for everyone. There is no access to the rest of Cuba, and transiting on and off base (via air only) may be difficult at certain times, as getting a seat on a particular flight is not always guaranteed. The weather is either hot or warm all year long, with little change in seasons. While there is an on-base hospital, those with medical conditions requiring frequent visits or treatment may not find their particular services available. Mail and package delivery also takes longer than at Continental United States locations. Security considerations can impact photography and other hobbies.
