Our cruise terminal has a season from October 1 to April 15 when the FTE will be 155 and visitor/transient will be 2,000 per day for 3 or 4 days per week (the other 3-4 days per week it would drop to 3 or 4 FTEs with 1 visitor/transient). From mid-April to end of September this drops to 2 to 3 FTEs and 1 visitor/transient per day. I think we should we use an average of daily FTE and visitor/transients for the year but would like to confirm. Your thoughts?

If I were in your shoes - I'd run the calculator for both situations separately and see if you end up in the same credit threshold. If you do - include a narrative to let the reviewer know you ran both cases and either way you end up in the same threshold.
If you don't (which you may not given the very different ratio of FTEs/transients in the two different scenarios), either go with the more conservative results and provide a narrative explaining that you have been conservative, or see if you can get in touch with a GBCI representative - present a case to them for something you think is reasonable and get in writing that they approve (which hopefully they will!)
Best of luck,
Melissa

You can always use a separate calculator for each of the different cases and then sum total it all up to show what the annual usage will be.
Download the WEp1 Sample LEED form, then fill it out and save it once for each of the usage patterns (being sure to cover the full year). Then create an excel spreadsheet as a summary -- enter one line for each usage pattern and a column each for flush fixture and flow fixture water use annual volume for both the baseline case and the performance case. (And maybe add a column at the beginning to explain what the usage pattern is.) Then have a totals section and calculate the percent reduction of water use. Basically you'll summarize all the gray rows on the LEED form in your excel spreadsheet.)
You will have to click the special circumstances box on the bottom of the LEED form and then upload all the sample forms and the excel summary sheet. (Include a brief narrative explaining your various usage groups and that you calculated them all separately and summarized it on the excel spreadsheet.) If you do all that in a clear manner, you shouldn't get questioned.

In the form Table WEp1-2 Fixture Groups Definition, consider creating separate fixture groups for the following scenarios you described, and include a narrative explaining your rationale:
- Fixture Group 1: 155 FTEs and 2,000 visitors - indicate the Annual Days of Operation based on 4 days per week between Oct.1 – April 15
- Fixture Group 2: 4 FTEs and 1 visitor - indicate the Annual Days of Operation based on 3 days per week between Oct. 1 – April 15
- Fixture Group 3: 3 FTEs and 1 visitor - indicate the Annual Days of Operation based on 7 days per week between April 15 – end of September
Hope helpful!
