Checklist

Checklist for quest suggestions (see guidelines):

• [x] 🚧 To be added tag is established and has a useful purpose
• [x] 🤔 Any answer the user can give should have an equivalent tagging (SCEE quests may not be answerable in all cases, but please keep this rare)
• [x] 🐿️ A survey is necessary (may require knowledge of the subject, though easy answering for everyone is preferred)
• [x] 💤 Not an overwhelming percentage of quests have the same answer (No spam)
• [x] 🕓 Applies to a reasonable number of map data (Worth the effort)

Ideas for implementation

Element selection:

nodes, ways with
         (
           leisure ~ resort
           or leisure = sports_hall and sport = swimming
           or tourism ~ camp_site|hotel
         )
         and !swimming_pool

Proposed UI: Solution A:

• Simple Yes/No Quest, just ask for a swimming_pool - easy as toilet availability quest

Solution B:

• Based on OutdoorSeating or SmokingAllowed Quest, ask for outdoor, inground, no and both (outdoor;inground).
