As such not really - but there was not a lot to do around the hotels, some of which were remote, and standalone on the beach - as is the new RIU Baobab Hotel in Senegal (Likewise same with Cape Verde hotels)
All-Inclusive had not been invented back then as a product. It was still HB or FB...
There are tourist attractions in The Gambia, and some offbeat tourism.
Montego Bay gained popularity in the 1970's with Thomson Sky Tours which is why Britannia AW got 2 707C's for a bit.
That was very much stay behind the hotel wall and don't go out....
The Mombasa coast beach hotels - same - very popular in it's day - may make a comeback???
