Invites & RSVPs
Send each guest a private link. They answer yes, no or maybe and tell you if they're bringing someone.
For people who host
Invite your friends to come and stay. Figure out where everyone sleeps, what everyone eats, what activities people want to do, and what everyone owes at the end...without multiple apps/docs/messages to manage.

Send each guest a private link. They answer yes, no or maybe and tell you if they're bringing someone.
Keep a bed inventory per house — 5 Kings and a Queen — and assign guests to real beds.
Post hikes, dinners, boat time. Guests claim spots; you see the list fill up.
Everyone adds what they want on hand. Check items off as you shop.
Log who paid for what, split it across the group, and see exactly who owes whom.
Paste a confirmation email or enter a flight by hand, and flag who needs a ride.
