你收到一封咨询信，请你以旅行社工作人员的身份完成任务。

Dear Ace Travel,

     I'm Li Ming, from the east of China. For the coming winter vacation, my family and I want to spend our

vacation in a foreign city for ten days. We would like to go somewhere not only warm but also interesting.

We don't mind how far we have to go. It has to be a place where we can swim everyday, and it would be

nice if our hotel is not expensive but clean and comfortable. We like to pay no more than $ 5,000 for the

trip. Could you please give us your suggestions for vacation spots?

Thanks a lot. 

                                                                                                                                              Yours, 

                                                                                                                                              Li Ming

      请你根据来信，从下列所给的地方中选择一个或两个符合Li Ming要求的地方，向他提出建议。
