My wife just gave birth a couple of weeks ago. For our 1st, we stayed in the single deluxe room - no package. For our 2nd, we just took the single bed package - much cheaper!
Those with a DBS card can opt for an installment plan.
actually if you are aiming for a 2-bedder, it may be quite worthwhile to go for the 4-bedder package.
TMC has relatively few 4-bedders so if they are all full, no choice but to upgrade but you still pay the 4-bedder package
