Upper Class Lounge passes

Hi All
Recently upgraded my seats from economy to PE flying LGW to St Lucia in June, just went to settle my bill and found out that the booking agent had got the price wrong for PE upgrade, so the invoice is £200 more than I was quoted!!!, after a few arguments and a quick letter to VA customer support they have met me half way with a £100 reduction and as a goodwill gesture will be giving me Virgin upper class clubhouse lounge passes
, is there an UC lounge in ST Lucia does anyone know?, as from the wording of the letter I cannot tell if this is access to lounge on return also?
Can none UC passengers normally purchase access to the UC lounge?
Nice customer support from Virgin [8D]
Thanks.
