Britannia Hotels hotels in Southampton

"My kids live with their mother, which is 2 hours away, my daughter had a dance so we booked this hotel specifically to spend the day with my children because it's advertised as having a pool. It does have a pool, but you have to pay £5 per hour to use it per person AND there's lots of closed off times that you can't use the pool. None of this information is shared on Hotels.com. I would NOT have booked this room had I known that upfront"
