Thank you Dhidra.
Spoke to her TI co today and they have said once she has completed her course of antibiotics and I can say the infection is resolved they will cover her. I need to ring back on Monday when they're finished when they'll be able to tell me if theres an addition to the premium.
Had a telephone call from her care manager today who has always been my best supporter among the professionals involved in Catherine's care and she was in DLP with her kids last week. Said it had been freezing cold and wasn't this really bad timing for us. She was a bit taken aback that I plan to go ahead but we talked it through and I told her I had planned for cold with thermals etc. and knew we'd have to spend more time in hotel than otherwise. In the end she said she would support me whatever decision I made because she knew I always acted in Catherine's best interests. Did feel a bit worried after that call.
I'm really glad you'll be able to go after all. You both definitely deserve it! I wouldn't worry too much; I mean its cold wherever you go at the moment, plus with an onsite hotel it only takes a few minutes to walk back if she gets too cold.
