Think about your priorities. Decide whether you want your visit to be more relaxing or educational and how many people will share in this experience.
Decide how far you're willing to travel. Lighthouse stays are available along the east and west coasts of the U.S. as well as in spots along the Great Lakes. If you're up for international travel, lighthouse bookings are available across the globe in places as familiar as Canada and Mexico and as unexpected as the Caribbean and Scotland.
Look for lighthouse stays in bed and breakfasts or inns if you want a combination of privacy and service. Several places have lighthouses on the property and allow guests to tour them but offer more modern amenities and dining options.
Consider a lighthouse that only has a keeper's home if you're looking for something more rustic. Most have running water, but not all have a phone, electricity or even hot water. Research carefully before booking to be sure your stay is workable for you and your comfort level.
Running the lighthouse is a responsibility with some of the lighthouse stays. Most lighthouses are owned and operated by government agencies, and you can't man the lighthouse. Some lighthouses are no longer operational. Conversely, other places let you do everything. Again, think about your level of investment before deciding.
Ask questions. When you're interested in a lighthouse, contact them for information. Some lighthouse stays are quite pricey, while others offer free stays for non-profit or educational groups. Find out the rules, the expectations for guests, about accommodations, transportation and meals.
Plan ahead and book your stay. Many places are booked well in advance, so be sure to solidify your reservation as soon as you've made a decision.
