At least once a fortnight a corps of caterers came down with several hundred feet of canvas and enough colored lights to make a Christmas tree of Gatsby's enormous garden.
In the text when it says came down with several hundred. It reminds me of Fortnite in which you jump from a plane several hundred feet with multiple people making you excited about the ensuing bloodbath. Gatsby uses the size and coloration of the lights to giver the reader/ people a sense of awe.
