It looks like forecast(fit, h=84) is re-using your old dummy_fest variable, which is incorrect. You need to forecast dummy_fest, and then provide that new data to the forecast function

Actually, take another look at the question: "There is a large influx of visitors to the town at Christmas and for the local surfing festival, held every March since 1988"

You've fit your model correctly. Now you have to figure out why tslm is dropping the dummy_fest variable from the model. =D

comment Clustering algorithms that operate on sparse data matricies
@MarkeD Could you post an example with the M1 matrix in my question above? I can't seem to get apcluster to run on that matrix in a reasonable amount of time.

@IrishStat Every dataset in FPP is non-simulated. Seems like great data to learn on...

comment Books for self-studying time series analysis?
@TomReilly Whatever the issues with any particular model, I'd still recommend the R language in general and the forecast package in particular to anyone looking to learn time series analysis. You really can't beat free, especially if your goal is education.
