I would recommend both options. Provision all of the heavy stuff like water (I plan on 1/2 -3/4 gallons per person per day, soda, beer, alcohol and mixers. We bring all of our main courses with us frozen and buy produce and chips etc there. Having just ordered this week I would say TICO had the best price for the beer we wanted. Alcohol from both Bobby's and TICO's and we will get fresh produce and bread from Riteway. In the past I have gotten most of what I wanted provisioning, but it is great to be able to pick up last minute stuff in person.
