There are several different styles of gazebos, from the very basic to those that come complete with towel bars, lighting and storage areas. It is wise to look at several, weighing the features of each, before making the actual purchase.
Some of the smaller gazebos only allow for window entry, by way of a ladder. Basically, there is only enough room in this type of gazebo for the actual hot tub. Larger gazebos come complete with a traditional door. Those with mobility problems should take this into consideration before making a final purchase decision.
Most gazebos will need to be stained, in order for it to protect them from the elements. This is especially true in wintry climates. Typically, they need to be re-stained, once a year.
