Hello folks. Looking for London advice. My wife and I are treating my parents to a 5 night trip to London in October (well...hopefully...my dad has Parkinsons and mentioned at Christmas that he wanted to see London while he still can...he already tires easily...has mobility issues...anywho apologize for the TMI). Would prefer to get both rooms on points but if none of these are decent options I can do points for one and cash for another at the Conrad. I'm Diamond fwiw, my mom and dad are nada.

Anywho, long story short, options we've looked at for which we have enough points for 2 rooms @ 5 nights (he doesn't need an accessible room):
Metropole (worried about taxis giving us trouble to/from HEX at Paddington)
Paddington (gets bad reviews here, but we only need clean/comfy beds...and attached to the HEX...won't be hanging out at the hotel)
Hilton Euston
Doubletree West End
Doubletree Hyde Park
Doubletree Tower London
Hilton or Doubletree Islington
Hilton Olympia
Hilton Kensington

Tube not the most important consideration as we'll need to take cabs as he cannot risk standing in the tube for any distance and again he tires easily. He'll try to force himself but that only takes more energy and makes his tremors worse. Many/Some affordable restaurants (aka middle class family out for dinner) in a few blocks walk max would be a plus.

Thanks for any help!
