Well, it seems that sometimes it can take a while to get the unambiguous facts!
I have spent the last couple of weeks exchanging phone calls and emails with Resort Services at Orange Lake.
The bottom line - and I have this both verbally and in writing by email - is that Orange Lake does not require payment of maintenance fees and taxes in advance when an owner deposits a week with an exchange company, no matter who the exchange company is.
They do require m/fs and taxes to be "current", meaning that they have to be paid up to date for the current year, (i.e., as of now, 2007) before releasing the week to the exchange company. This, I believe, is actually what they were saying in their reply to Marty's enquiry.
I've pointed out before in this thread, Marty says that it is only Redweek's requirement because it is a resort rule, which I have now found out it isn't.....
