At first, it would be good to note restrictions for Geocaching.com Basic Membership. Premium users have only a restriction of downloading 6000 full details of the Geocache per 24 hours period. These restrictions are from Geocaching.com side.
Note: Always, when you will want to download full details, you will be asked if you really want to do it including information about time, when the quota will be reset.
