Welcome to forum, @Lance-R !
I would normally not accept GP for several reasons:
It is my primary residence. Your times might not work for me leaving my home.
I prefer reciprocal exchanges. The part of building a relationship between exchange partners is important to me, for me the “community feel” of exchanges is important and GPs are too transactional in nature to measure up to that.
Although I am going on vacation, my household might not. I have grown kids that are often home from uni during the holidays, and they like to earn some money and stay in our home while I’m away.
Our dogsitter might stay in our home while we are away.
Just some things that might hinder me from accepting.
In addition - all members will often ask quite a few before finalizing an exchange. We are people with lives - family, work, obligations - it takes some effort to find a partner where everything - timing, location etc all align. I need my employer to confirm my holiday, I might have planned some days at another time of the year, my home needs to be vacant, tidy and clean (sometimes I will prefer a hotel because I don’t want that extra chores).
Not to discourage you, but to share some insights on what might be going on. This can help navigate. In general it helps to approach members that align with your criterias, and also members that are not flooded with requests. Members living in prime locations can afford to be picky, while members in more “oh, where’s that?” might be more forthcoming - AND offer more unique experiences that you wouldn’t find without HE.
Newbies might also need to lower expectations, as some members might be hesitant to unexperienced exchange partners. For a newbie, I think I would be more comfortable doing a reciprocal exchange than GP.
Just my thoughts, for whatever it is worth. Others might see things differently, for sure. I hope it can help so that you get nice exchanges. Best of luck!
