I'm planning a vacation in Europe at the end of the year. Some destinations are fixed but some are not. I'm with a group and have set activities for the fixed destinations but I want to explore some more of Europe while I'm on that side of the world.

I was wondering if there are resources for 1:1 private tours that doesn't cost an arm and a leg? The tour by locals I've seen are designed and priced for group tours.

If I must spend a lot on it I would much prefer it to be with a cute college-aged girl with extras available, in the same vein as massages with an HE.

If there isn’t, this could be brilliant business ideas.

Can’t link in ratings, so here goes: https://www.showaround.com/

It’s a Europe-based agency, and some of its local guides offer tours for free

Never tried it myself, but would love to hear about your experience if you do.

I read this a long time ago.
I was never able to put it into practice, but maybe it'll be a bit easier with the internet being more widespread.
It does require you to be open about your 'needs'.

This was when wireless data wasn't a normal thing to have.
The poster mentioned they had hired a translator/guide for the day in China for actual touristy stuff.
Poster planned the activities and was a lone traveler and posted on CL or something like that in China.

At the end of the day, he asked the translator to help him with scheduling a companion for the night.
Instead, the translator offered to be his companion and he had a nice time.

Don't mention the hobby in the advertisement, but when communicating 1:1, bring up if they are okay with translating for you at the red-light district or outcall services.

When I was in Europe years ago, I used myspace at the time to message local hotties saying I was in town for a couple of weeks alone and would like to hang out and be shown around. I had a few bites and picked one, she would pick me up and would drive me around after a few days she said she did some digging and brought up the SO...whoops.  Never got anything other than a hug but the hunt was

you could also try locate for the town your heading to. place  an advert asking  for a guide in the personals add section a few weeks before .. that could work.

A few years back (mid-2010s), I used Seeking to meet up with a lady who acted as a tour guide for me.

In my message, I put I was visiting (City) for a few days and was looking for a local who could show me around. I put this out to a few girls on the site and usually got 1-2 that I ended up actually meeting up with. Because it's Seeking, they know your interests go beyond the local hot spots, but you do get to see more than of the city than you might on your own.

As far as the arrangement went, we met up the first day I was there for dinner near my hotel and we got the arrangement part. I think it was about 2-300 local currency per day, plus expenses. It's been a few years, and I'm older now, so expect at least 300 these days.

Mind you, this was in Canada and Germany, fairly safe countries, not sure if I'd do this in certain parts of the world.

These days I use a site called SugarDaddyMeet.com (SDM) mostly (it's pretty popular in Canada) but Seeking is still the best bet for overseas, and it has a much larger global membership.
