international hotel rate question

Anyone know what “GIT” and “FIT” mean in the context of hotel rates? I found them on a Sri Lankan hotel website:
http://www.aitkenspenceholidays.com/kandalama/hotel.htm# (“tariff rates” link)
and have seen them on websites for other hotels around the world, but haven’t been able to find a definition.

GIT rates are group rates. FIT rates are for individuals.

It pays to be a GIT :wink:

Example cite.

Just to expand, the acronyms are for and Group Inclusive Tour and Fully Independent Travel respectively.

Thanks!
