There is a variety that is smaller, Angraecum. sesquipedale var. bosseri. Some of the bosseri are said to bloom twice a year, November and April. (?) No idea of the truth behind it, though.
I have gotten rid of nearly all my large orchids but I think the sesquipedale is worth the space. I have no idea if mine is the smaller or larger type but it is going to stay in the collection, mainly because it was a rescue and I have now gotten into the habit of pampering it. :|
If you do not have the space for the sesquipedale, there are Angraecums for every size and environment.
