No, it's not advisable to have multiple travel insurances for one trip. Most policies will not pay out if you have overlapping coverage. It's better to choose one comprehensive policy that meets all your needs
It's not illegal to be dual insured, but it can make claiming more complicated. For example, if you needed medical care abroad and had two travel insurance policies that could payout for the claim, you won't get double the money. Instead, the insurers would decide how they will split the bill . . . .

even at the Olympics, the poorly educated American athletes have to run or jump meters, not yards or miles 😎😂😎😂 that must be so staggering difficult for them 😎
