Sarah proposes opening family activity resorts that offer a variety of winter and summer activities, restaurants, accommodations, and babysitting services. The resorts would target people of all ages and from different countries. Market research found that 100% of survey respondents were interested in such a concept and 33% would use it weekly. The resorts aim to fill a marketing gap and could charge $50 per day, with family discounts. Sarah plans to open locations in Europe initially and then countries without much snow, seeking financial support and hiring help along the way.
