How MMI works

Will it live up to the brochure?

We turn the everyday worries of travellers over 60 into 11 simple indicators anyone can repeat, and one score out of 100.

What we measure

Five pillars. 11 indicators.

Every indicator answers a question a traveller would actually ask, and scores 1 to 5 against fixed bands. Open a pillar to see exactly what we check.

1Health & Safety35%

Emergency hospital

“If I fall ill, how fast can I reach an emergency department?”

Driving time from the tourist office to the nearest 24-hour emergency department. 5 = 15 minutes or less.

A comfortable day

“What will a comfortable day cost me?”

Comfortable months

“How many months a year can I go without suffering heat, cold or rain?”

Published in full

Don’t take our word for it. Read the book.

The MMI Charter sets out what we stand for, and every rule a score is made from: every indicator, every score band, every source, word for word. We publish all of it, so anyone can check our work.

Where the evidence comes from

Checkable in minutes. By anyone.

No paid databases, no site visits, no favours. Every figure comes from a public source you can open yourself.

Some sources, like hotel and tour listings, rely on traveller ratings. We use them only as fixed filters, the same way for every destination.

How an evaluation works

Six steps, every time.

  1. Fix the starting pointThe official tourist office and the top 5 sights, set before research starts.
  2. Capture the evidenceEvery figure, with its link, date and screenshot, captured within one 14-day window, so all the figures reflect the same moment.
  3. Score each indicator1 to 5 against fixed bands.
  4. CombineIndicators make pillar scores; weighted pillars make the score out of 100.
  5. Second checkAn independent checker re-opens every source and confirms every figure.
  6. PublishWith the method version, capture dates and any warnings that matter.
Example: arrival

How one indicator is scored

Fastest public transport from the airport to the tourist office, leaving 10:00 on a Tuesday: 52 minutes, one change.

That falls in the 46–60 minute band, and one change carries no penalty.

The MMI score

How the 100 points add up.

35Health & Safety+ 25Getting Around+ 20Cost+ 10Climate+ 10Things to Do= 100MMI score

Each pillar earns its share of the points by how well it scores out of 5. A pillar scoring 4 out of 5 earns four-fifths of its points.

Our rules

What MMI will never do.

  • Guess. Missing evidence is left blank. A destination with a gap gets no score until it’s closed.
  • Bend the rules for one place. No rule names a destination. Every place is measured the same way.
  • Treat AI text as evidence. AI helps us work, but every figure must come from the source itself.
  • Count the same evidence twice. One named source for each fact.
  • Hide a correction. Every correction is logged and dated.
Good to know

What the score doesn’t cover.

Hotels and restaurants aren’t scored. Mature travellers choose a destination for what it offers, then find a hotel and restaurants to suit them once they’ve decided, so we give practical advice instead: where to stay, dining tips and senior discounts.

Specialist disability access isn’t measured. MMI is built for active, independent travellers. If you have specific access needs, check with the destination directly.

Personal taste is yours. We measure how well a place works, not whether you’ll love it.
