Tis the time to get ready for bachelor and bachelorette parties at Put-In-Bay for 2017! We see this question quite a bit and it brings back fond memories of past party weekends. Some information to get you started can be found at http://www.putinbaybacheloretteparty.com where you will find info on lodging, bars, entertainment, what to bring, drinks, etiquette, etc. It's a good starter resource.
A second source for more specific lodging would be the reservations site at http://www.putinbayreservations.com where you can get more detailed information.
Now, for some more directed advice. You will need to think about narrowing down your number to something more specific before you start your booking, because your options will be very different depending on whether your number is 6 or 12. Hotel rooms generally sleep 4, suites sleep 6, waterfront condos sleep up to 12, and vacation rental homes sleep up to 16. All of the hotels are downtown and walking distance to the "strip", so no worries on that part. Rental houses and waterfront condos though are all over the island and may or may not require a taxi to get back and forth, but have beautiful views and more amenities.
One of our favorite hotels is the Bay Lodging Resort because it has a good variety of rooms (a dozen suites that sleep 6, and two specialty rooms that sleep up to 10), it has a pool (albeit smaller) with a bar as a good starter for the day, is walking distance to the other hotel pool bars (which get way crowded) and downtown, and is relatively peaceful in the evening if you want to actually sleep at night (but hey, who does this at Put-In-Bay anyway?!?).
One of our favorite rental units is the brand new Put-in-Bay Waterfront Condos which is located behind the airport right on Lake Erie with beautiful views of the water. They sleep up to 12 girls, have a nice little patio to play yard games and drink beverages during the day. There is also a large private pool and pool deck that you can take your own drinks to (no bar) and enjoy the sunshine. Later on, catch a taxi to go down to the strip at night to go bar hopping.
If you have AAA, you can get discount Jet Express tickets at their office before you leave!
The most important thing to remember is... have fun! And book early. Weekends fill up FAST for the larger hotel suites/condos and homes. Some weekends are actually nearing sold out from what we have been told.
