What I remember the most from CCS is eating out a lot, those restaurants served so many side dishes and great food ^
I'd say that the cable car to the El Ávila mountain is worth a visit, great views from the city, the mountains and the coast.
The official exchange will make everything seem expensive, so if possible, ask a friend or acquaintance to help you exchange USD to Bolívares at a better rate than the "official" one.
The official one is 4.3 VEF to USD, the unofficial one is 8 VEF to USD, almost a 100% difference. From my impression everyone used the unofficial one to calculate foreign prices, as the amount of USD a Venezuelan can obtain at an official rate is limited by law.
