一度 - one time
ビーチリゾート - beach resort
飽きる - get tired, give up 飽きない - never get tired, never get tired
〜〜や〜〜 - andかorを使える

Going to cities and/or tourist spots is enough (for me)
〜〜だが - but
何回行っても - no matter how many times I go (これはちょっとむずかしいけど”no matter”はよく使う表現） 動詞っても - no matter how many times I 動詞
Going to most tourist destinations once is enough, but I can go back to the same seaside resort many times and never get bored of it.
この場合、次のような言い方ができますよ。
ーGoing to most tourist destinations once is enough, but I can go back to the same seaside resort many times and never get bored of it.
「多くの観光地は一度行ったら十分だけど、同じ海辺のリゾートは何度行っても飽きない」
once is enough で「一度で十分」と言えます。
