Should the laptop be ok to be charging over there on 110v.

yes

If shaver is 240 volts only would it run but slower.

I'd expect it to be more like a rough plucking, than a shave

It will try to run at 60Hz rather than 50Hz and may not work at all.

Famous brand rubbish US made mains shavers sold in the UK mostly at Xmas
used to rely on a 60Hz mechanical resonance to work properly. Once most
people tried a proper European made shaver they never went back.

A decent proportion of hotel bathrooms have 240v ac available in them.

Also for charging phones will they charge but at a slower rate.

Should just take more current from the mains (or take it for a larger
fraction of the mains cycle) and charge the same.

Most PSUs for phones and laptops really don't care about the mains input
voltage provided that it is above 100v and below 260v. OTOH Some US made
kit is notorious for only working on US 110v mains at 60Hz (transformers
that will saturate on 50Hz supply) with shoddy transformers and
insulation that is barely up to the job.
