Deskpass VS ViaHero

Deskpass.com has a free month trial, I think it gets you 6 credits. You can use a credit for 1 day at any of the coworking spaces on their list. There are plenty in the Denver area that accept the credits. Should get you through 3 weeks using 2 per week.. Source: about 2 years ago

There's a website (that I help run) where you can ask these types of questions to locals for free - viahero.com. You can pay for more in depth planning but the local planners on the site are happy to answer general questions like this and they can be really helpful for specific or niche stuff that only a local knows about.

Apologies ahead of time if this is not allowed but I help run a website where you can ask Italian locals these exact questions for free - viahero.com. If you want to have them actually help plan out your trip in depth you can of course pay and they will put together a whole customized itinerary and map for you but you can message for free with no limits and many are happy to answer these sorts of general questions...

Not sure if this is against the rules, but I help run a website where you can ask these types of questions to locals in Puerto Rico for free - viahero.com. You can of course, pay them to help you with more in depth planning, but there are no limits on the free messaging and they are usually glad to share general recommendations for where to go and what to do.
