Can you elaborate on whether $100 a day is a sufficient amount to live on in Dubai? Considering the high cost of living, including accommodation, transportation, and dining out, would this amount allow for a comfortable living standard or would it be more of a struggle? Are there any areas or neighborhoods in Dubai that might offer a more affordable cost of living, or would $100 per day be challenging regardless of location? Additionally, what would be some alternative ways to stretch this budget or save money while living in Dubai?
