Jamaica?

…no, she went of her own accord.

Hello, I was thinking of booking a holiday to Montego Bay for someone. I’ve never been and so have a few questions please.

1. IHG & Hilton options seem to consist of only the Holiday Inn resort and the Hilton Rose Hall. Would welcome any opinions of these two places.
2. If I book through BA holidays, am I right in thinking these two properties won’t recognise status or award any points?
3. If I book directly with the hotels, will they allow points bookings if I don’t go there myself? similarly, would status benefits apply (inc room upgrades and such like).
4. I think the first 2 weeks of December are decent for weather and pricing. Looks that way to me based on limited googling, but would appreciate an experienced opinion.
5. I assume there is no way to use a companion voucher when I’m not travelling, right? I don’t want to pay full cash fare for a premium cabin for someone else so I may have to pay for economy tickets. Never done an upgrade with avios, is that a reasonable option here do you think?

Thanks.
