Thank you RJP, I will make the grammar corrections with the next adjustment of the website.
The reason I took down the 'one tank dive' and 'two tank dive' is because I got tired of people asking if they could do the two tank dive with one tank because they didn't think they could lift two tanks, or because their BC would only take one tank!
Try this:
Daily Dive Trips:
Morning Trip: two dives - $80 (9am departure)
Afternoon Trip: one dive - $45 (2pm departure)
Night Dive: one dive - $70 (departure TBD)
The night dive "surcharge" is currently unclear too. Seems like you offer a one-tank night dive for $70, right? ($45 for a one-tank dive, plus $25 "surcharge") But as written it could be read that you also offer the option for a "two-tank" night dive for $105 ($80 + $25) or is that $130 ($80 for two-tank trip + $25 surcharge for EACH tank?)
I would ditch the word "surcharge" altogether, it sounds like some sort of "punishment" for wanting to dive at night. If the night dive is $70, just say so.
