Questions in grammar:

1. There are a lot of "surprise" OR "surprises"?

2. "There is a holiday in next week" Or "There is a holiday next week"?

3. Most of the security guards in this villa are lack of politness. ---> is this phrase okay? sounds common and natural? if not, how do i say this?

4. Grammar check pls: "They do not have the basic greeting and salutation to the people who live in here. Since they are the security in this villa(and this villa is pretty small), they are supposed to know us, at least our last name. Awfully, every time when they talk to us, they only say "YOU", but no salutation like Mr XXX or Mrs XXX. This is very rude of them."

1. "There are a lot of surprises."

2. "There is a holiday next week."

3. "are lack of politeness" is ungrammatical. You can say "Most of the security guards in this villa lack politeness", or just "Most of the security guards in this villa are impolite/rude."

4. "They do not use basic polite greetings when speaking to the people who live here. Since they are the security in this villa (and this villa is pretty small), they are supposed to ["supposed to" suggests that there is some agreed code of conduct that says so. If it's just your opinion, then you should say "they should / ought to"] know us, at least our last name(s) [If you are talking about several people with the same last name then use "name". If the people have different last names then use "names".]. Every time they talk to us, they only say 'you', never 'Mr X' or 'Mrs X'. This is very rude of them."
