We are flying out later in the year. It is complicated but we have rented a villa for 3 weeks. The in-laws are staying for the full 3, we are staying for the first two and my sister-in-law and her brood arrive 3 days after us. So for the 3 days we have a bit of room a good friend of mine is flying down from LA so we can catch up go to Kennedy and so on. Someone in the family has thrown a spanner in the works and said that it is against Floridian law to have someone 'unregistered' staying at a villa for any length of time.

Is this the case or has someone got the wrong end of the stick??
