But why do I have to explain any part of my personal situation? The question posed had nothing to do with me personally so I'm not sure why anyone had to go there in the first place. Why do I have to state I've already bought? Why do people assume I haven't bought yet? Now you're reaching...
Again, if you mention something in your post, people will take that into consideration when giving advice, and they should. If you don't want it commented on, don't divulge it, it's that simple. People assume you haven't bought yet, because you never mentioned you had. That being said, after more thoroughly reading the first page of posts, people did go in a completely different direction than your intention, but I suppose "welcome to the world of message boards"
Back to your original question, you have inspired me to update my own spreadsheet to reflect my Europe vacation of a couple of months ago. My purchase price of my timeshare in 2009 was $3300, I have paid $3150 in maintenance Fees, $387 in lock-off fees, $774 in exchange fees, $267 in Interval Fees and $307 for a getaway fee, for a total of $8185.
In those 3 years, I have stayed in 1-bedrooms in Ko Olina, Timberlodge, Frenchman's Cove (actually 2 but only need 1), and one TBD. I have used 2-bedrooms in Newport Coast, Marbella, and Marriott's Village d'Ile de France. This totals to 70 hotel room nights (I don't stay in condos, only resorts). I estimated the following costs per hotel room night for a place I would likely pay to stay at: Ko Olina: $225, Newport Coast $150, Timber Lodge $150, Marbella $225, France $225, Frenchman's Cove $200, and my TBD night at $150. This brings my total if staying in hotel rooms to $13475, leading to a savings of $5290, plus the obvious benefits of timeshares over hotel rooms.
I did not factor in time value of money, because nothing is paying any interest anyhow, and I did not pay any interest on any of the above items.
Any suggestions for adjustments would be greatly appreciated.
