WOW! I'm so sorry! I guess this is proof that I'm not a Terminator, basic user error! Here are the correct figures.
$492.00 partial
$632.00 full
$682.00 preferred
$792.00 premium
$2,700.00 cabin (all before taxes)
Big thanks to kc5grw for debugging for me! You are very astute to pick up on where the error was. I know what happened, I had to add a new "rate season" for the cabins during the Jan marathon and failed to re-sort the lookup column... duh! Thanks again. The corrected version is uploaded.
