I suggest that when you create a row for your reservation that you protect that row so that only you or @omarsultan can edit. To do this:It's not locked for editing when others are editing. I noticed cursor/tabs moving when I looked. My info is 80% correct, but in CA and July date.
1) Click in the leftmost cell with your row number
2) Right-Click and choose Protect range
3) In the dialog, provide your TMC name and click on the Set Permissions button
4) Uncheck everyone except for Omar and add yourself as an editor for the row
