My next trip

I'm planning my next trip with my girlfriend over the next few days. However, we are (currently) in two minds because we have two preferred destinations: Cancún and New York.
My girlfriend would like to visit Cancún because she loves the beach, the aquatic parks and all-inclusive hotels. In contrast; I like cities, the skyscrapers and the shopping malls. Furthermore, I would like to practise my English and can visit (both) central park and central perk (the bar from the TV series 'Friends'), though I would not mind the relaxation that a beach can offer.
Finally, the New York trip will be more expensive but I have always thought that the because vacations are only once per year; they should be unforgettable.
If you have visited Cancún and/or NY, what would you recommend?
(Thanks for reading, I'm looking forward to your corrections)

We have two destinations in mind: / We're deciding between two destinations:

Remember that English does not use definite articles with nonspecific plurals/uncountable nouns (I like chips, books and tea) however; notice that 'the beach' replaces the plural 'beaches' in your sentence. Also: 'the outdoors', 'the sea', 'the ocean'.

'practice' = noun

'practise' = verb/adjective (note that only 'practice' is used in US English - I'm from the UK so don't take my word on that though!)

I amended the last sentence simply to sound more polite ;-)

My next trip

During today, I am going to plan my next trip with my girlfriend. However,we are rather stuck since we have two proposed destinations (Cancún and New York).
My girlfriend would like to visit Cancun, because she loves: the beach, the aquatic parks and all inclusive hotels. In contrast I like the city, the skyscrapers and the shopping malls. Besides, I would like to practice my English and be able to visit central park as well as central perk (the coffee shop off of the TV series Friends), Although I would not mind the relaxing atmosphere offered by the beach.
In addition, the New York trip can be more expensive, but I have always thought that a vacation is only once per year and should be unforgettable.
If you have visited Cancun and NY, What would you do?

I would recomend New York, however if you're thinking of going between November and February I'd say choose Cancun, as the New York weather will be terrible and the trip will most likely be ruined.
