Flight training in a Cirrus SR22 to earn your Instrument rating can be done relatively quickly. In some cases in as little as 7-10 days. This depends on what you have already accomplished.
Look for an airport that is in Class E airspace and has multiple instrument approaches so that you can maximize your time in the air.
One great location is the island of Lanai, Hawaii. This Class E airspace has an ILS DME Arc, and VOR-A, and GPS approaches along with holding patterns nearby. This is one of the most efficient places to train.
Good crosswinds also make for excellent practice at this airport.
