Review for Holland America Line - Volendam Review For Riverside Casino & Golf Resort Google User Mar 19 '18 at 1:02 Riverside is located in easy central Iowa, just off Interstate 380. The hotel rooms I've stayed in at Riverside were very clean, nicely decorated and comfortable. They have large walk-in showers with floor to ceiling glass separating it from the main room (a motorized curtain can also be used for more privacy). The casino is fairly large with tons of slot machines and plenty of table games. They often have promotions of giving away various items (cookwear, for example) to guests who earn a certain amount of points by playing slots or tables. View full site to comment or like
