What time of the year in the winter I believe they're a dollar or two cheaper as Chad said and also his recommendation of the new Aqua Center is very nice and $4 but limited times
Yes you can buy passes to swim without staying but I think its 12-15$ for each wrist band.if you want to swim indoors but not get a room go to the aquatic center in Sioux falls its about 4$ per person.
You have to have a room pretty sure
