thanks for the replies. wala kaseng tour dates na sakto sa alis namen, so i'll just ask travel agency to arrange hotel and transfers namen and ask hotel for tours that we can join. here's our IT (copied a tour itinerary from Disney Tours):
Day 1 (Mar 28) - 4pm arrive in London
Day 2 (Mar 29) - Double-decker bus, Westminster Abbey, Buckingham Palace
Day 3 (Mar 30) - St. Paul's Cathedral, Thames River, London Millenium Footbridge, Tower of London, London Eye, Big Ben

Day 7 (Apr 3) - Notre Dame Cathedral, Eiffel Tower
Day 8 (Apr 4) - Disney Paris
Day 9 (Apr 5) - Disney Paris
Day 10 (Apr 6) - 1pm fly back to Manila
I'm still trying to extend our booking to April 7 or 8, pero as of now ubos na kase promo fares for those dates. My kids are used to travelling, so no problem dragging them to walk all day

I'm still trying to convince my sister to join para may isa pang adult. I plan to bring one suitcase lang, para madali when we have to transfer hotels.
I need to redeem my free ticket from HSBC na kase by the Nov 25. Since next year pa yung travel date namen, January next year ko na din papasked yung visa submission/interview namen.
