The going rate for a week of group swimming lessons varies depending on the location, the size of the class, and the experience of the instructor.
In general, however, you can expect to pay anywhere from $10 to $20 per lesson. If you are looking for a more affordable option, you may want to consider taking lessons at a public pool. Public pools typically offer group lessons for a fraction of the cost of private lessons. However, it is important to note that public pools may not have the same level of quality control as private pools.
If you are willing to spend a bit more money, you may want to consider taking lessons from a private instructor. Private instructors typically charge more than public pool instructors, but they may be able to provide you with more individualized attention. Additionally, private instructors may have access to pools that are not available to the public.
Ultimately, the best way to find out the cost of a week of group swimming lessons is to contact your local pool or instructor. They will be able to give you a more accurate quote based on your specific needs.
