In addition to your booth fee, there are additional costs that Cultural Survival does not cover (transportation, lodging, food, etc...). Cultural Survival does not provide transportation between your hotel/lodging and the event locations.
To factor in costs, please consider:
Meals
Eating out may cost about $30-60/day.
Before reserving a place to stay, please use maps.google.com or Rome2rio.com to determine travel time to and from the venue. Some hotels are very close via public transit, and others are not. Taxis and Uber/Lyft cost anywhere from $10-35 per trip depending on where you are traveling from in Boston.
Lodging
The closest option is The Omni Providence Hotel just a four minute drive from the WaterFire Arts Center. The Omni is about $135.00 USD per night. For more affordable options vendors are encouraged to look into hostels in Providence such as Michie Hostal (also check this link and this link too)
