Help with stay/hotels in Paris Amsterdam London
Traveling to Paris, London and Amsterdam/Brussels this summer (July end-early Aug). Haven't decided between the last two yet (booked flights to Paris and flying out from London). 4 of us - 2 adults and 2 kids (13 and 7) - does that make 3 adults and 1 kid for European hotels? Do I need to book two rooms for 4 of us?
I need help with planning accommodation at these places. Looking to stay 4 nights in Paris, 4 nights in London and 1 or 2 nights in Amsterdam/Brussels. I have 130k MRs, 350k URs 60k Hyatt points. Planning to visit major tourist landmarks so I guess best is to stay in the city close to public transportation/major landmarks.
Marriott? Hyatt? other options? not looking for luxury experience, reasonable points redemption.
VRBO and Airbnb are ok too but can I book these with points or redeem using points with any of the cards (Venture X may be, but do not have many points left to redeem)?
