The last week of January is not usually that crowded. If you get a North Swell that can drive more boats into anchorages not effected. That’s mainly a issue around Jost. I might suggest you consider putting a skipper onboard for the first night or two and practice anchoring. It’s a essential not optional skill. In all my years down there my only issues at night have been on Mooring balls not anchored. The balls take a lot of abuse.
