As a follow-up--I contacted Maribel Roncal, but they asked for a wire transfer. I bank with a credit union that doesn't have international wire transfer services. Western Union will only send to an individual, not a business. I went to Charles Schwab and can open an account there, but they will only put money in an account with a cashier's check (no cash, no personal checks, apparently no domestic bank transfers), and they then charge $25 for an international wire transfer, and I can't make the transfer until 10 business days from opening the account, which is later than Maribel Roncal is giving me to pay. I've written to see if they have a Paypal option. With the albergue's San Fermin rate, the cashier's check, and the wire transfer, I'm now looking at about $66 if I want to stay in this albergue (assuming I can even work it out, which I'm not hopeful about).
