A family entertainment center (or centre), often abbreviated FEC in the entertainment industry, (also known as indoor amusement park or indoor theme park) is a small amusement park marketed towards families with small children to teenagers, and often entirely indoors or associated with a larger operation such as a theme park.
 They usually cater to "sub-regional markets of larger metropolitan areas."
 FECs are generally small compared to full-scale amusement parks, with fewer attractions, a lower per-person per-hour cost to consumers than a traditional amusement park, and not usually major tourist attractions, but sustained by an area customer base.
 Many are locally owned and operated, although there are a number of chains and franchises in the field.
 FECs are sometimes called family amusement centers, play zones, family fun centers, or simply fun centers.
 Some non-traditional FECs, called urban entertainment centers (UECs), with more customized and branded attractions and retail outlets, are associated with major entertainment companies and may be tourist destinations.
 Others, sometimes operated by Non-Profit organizations as Children's Museums or Science Centers, tend to be geared toward edutainment experiences rather than simply amusement.
 FECs may also be adjuncts to full-scale amusement parks.
An amusement park is a park that features various attractions, such as rides and games, as well as other events for entertainment purposes.
 A theme park is a type of amusement park that bases its structures and attractions around a central theme, often featuring multiple areas with different themes.
 Unlike temporary and mobile funfairs and carnivals, amusement parks are stationary and built for long-lasting operation.
 They are more elaborate than city parks and playgrounds, usually providing attractions that cater to a variety of age groups.
 While amusement parks often contain themed areas, theme parks place a heavier focus with more intricately-designed themes that revolve around a particular subject or group of subjects.
