2 questions - future discounts & personalized voyages

[lkbside]

A couple questions -
I'm looking at Vietnam Renaissance - voyage 1437 and alo Indochine Sojourn - Voyage 1438. Right now there is a 50% discount on Voyage 1438, but only 20% discount for prepayment on 1437. Does anyone know if a further discount is likely for 1437 or typical lead time for deep discounts?

Alos, has anyone ever booked a personalized voyage - ie embarking or disembarking at different points than the set voyages? Any chance for discounts then, or do they hold to daily brochrue price?

Thanks for your help.

I don't know the likely hood of getting a lower rate on #1437 but don't forget you get an additional discount for booking the two cruises back to back anyway.

Another Question,
If the price of a Cruise drops after you're full payment,how is the credit given to you?On most ships they give you a shipboard credit to use for your wine and drinks,but on Silverseas all is included.Do they issue you a credit card refund, or just the ship board credit.Or a credit toward another booking.
