holiday buggy combinations!! what would you do??

[fairimum]

We are going to Portugual with OH's parents in August... DD1 will be just 2 and DS1 will be about 4 months (due any day). I just can't decide what to take.... we have a Phil and teds sport so could take that... also have an icandy cherry which I love and loved clipping carseat to for DD for short trips (do have P&T car seat adaptor too!)... but then would have to decide if to take the seat unit (think DD started going in for short periods about 5 months though, but she hated the carry cot....) or the carry cot... which would be very useful for him to sleep in (if still fits in there!!) - if we take the icandy, the inlaws have a lay flat cheap stroller that can use for DD.... so what would you do?

just take p&t for them both, or take icandy for baby and lie flat stroller (or poss luna) for DD??

never traveled with little ones before... will also be taking sling of some description, poss 2 as still using connecta for DD and have a wrap which can use for baby when not too hot...

thoughts/ideas very very welcome!!
