I look for high season, resorts to be about 50% ready and maybe 10-20% of the restaurants to be operational. %50-70% of Front St businesses might be ready but the infrastructure will take a long time to put back together before this can happen. This can not happen by High season by any means. Heck before any repairs can take place you have to have materials, work force and electricity for the workers tools to operate.
Resorts might be able to get things done quicker than businesses that have the insurance and means but St Maarten will take years to be fully recovered.
We are still planning on being there this May but don't expect to much.
