You got volun-told to plan it. Twelve mates, twelve opinions, one budget nobody agrees on. Manta turns the chaos into one plan everyone can see - and pay their share of.

You didn't ask for this. Manta does the herding - polls, reminders, and the awkward 'who's actually in' bit.
Split it fairly, see who's paid, and nudge the friend who never does - without you being the bad guy.
Float a few options, let everyone vote, and lock the weekend the most people can make.
The adrenaline crew, the foodies, the one who just wants a big night - each gets their thing in one plan.
Manta was built for exactly this group: a crew that wants different things, on one trip, with one person stuck organising. Everyone joins by link - no app required - adds what they want, votes, and the plan converges. You stop being the travel agent.
Booking stays off-platform and fair: pick stays and activities, split the cost per person, and book with the supplier directly. We never touch your money.
Pick a base - each links to its full guide.
Add a thing to do - each links to its activity guide.
