We had a similar experience, although there were 5 of us. I can confirm that it’s better not to skimp on size: even a small amount of extra space greatly affects comfort. There are usually several standard routes along the coast, but a lot depends on the weather and the time of year. There are time restrictions, and overtime hours are paid separately. Most yachts have basic music, but it’s better to discuss food and drinks in advance to avoid surprises. In general, if you clarify everything before going out to sea, the trip will be calm and stress-free.
