As others have indicated you can rent from more than one member. I would be hesitant to do so though...only because renting from one member is involved enough. I wouldn't want 2 different sets of terms, 2 contracts, 2 sets of contact information, etc. One of everything is plenty especially if this is your first time renting.
I notice you haven't posted on the rent trade board yet. I suggest you do and the sooner the better. Include as much information as you can: dates, resort, villa size, dedicated vs lock-off and in the case of BCV two queen beds vs a queen and pullout in the second bedroom. State your desire to rent from only one member (this will eliminate some of the "I have 58 points that expire in June" replies). There are some owners, like myself, who have that many points to rent but I no longer post listing my desire to rent points. I choose my rentals by answering posts from families who are looking for points. I select rentals that best suit me: rentals of over 275 points, close to the begining of my use year (June) and within the reservation window of my home resort (OKW). I'm absolutely certain you'll be able to get ALL the points you need from one member. Let the member seek you out...a 675 point rental is a great rental in my book.
I happen to have enough points available for your stay at BCV but since my home resort is OKW I wouldn't be able to reserve until January. Good luck.
