The second you mention "photoshoot" to anyone in a hotel, they are going to see dollar signs in their eyes. Commercial shoots pay premium prices for locations. In addition, many hotels don't want to be associated with specific types of content, and may flat out tell you that you are unwelcome at their property if you are looking to shoot content they aren't interested in being associated with.
A couple of things to consider as options:
- You may want to try AirBNB / VRBO / Craigslist Vacation Rentals section. These are typically handled by private owners (or smaller management groups) who many have a need for a photographer and could possibly exchange services.
- At some point, you likely will have some prospective clients in mind for these shoots (besides the subjects themselves). Websites, magazines, etc. You may be able to find a smaller client in this area who would be willing to pay for the location fee (IE: the hotel room) if you provide 2 or 3 shoots for them from the location. Instead of costing $100 to $200 for a single shoot, the cost is only $33 to $66 per shoot, which is much cheaper.
- If this is truly the direction that you think will build your portfolio, then find a way to earn the money elsewhere and be prepared to spend the money yourself as an expense. As the saying goes, it takes money to make money. You may have to swallow the cost and hopefully knock 3 or 4 shoots out with one hotel rental fee to ensure you can book future gigs. In theory, a single paying gig will more than cover the cost of the hotel room, so investing $200 now should lead to much more than $200 in long-term revenue.
I don't know how old you are, but a night in a semi-decent hotel should be affordable to nearly anyone who owns a 'decent' amount of camera gear. I realize that the gear list in your signature is a bit on the 'junior' / affordable side. You likely have more to learn by continuing to shoot new subjects in situations and locations that you have 'free' access to than by trying to pay for a location fee.
